The FS100R12PT4 from Infineon is the 6 - IGBT4 generation high-voltage power module in EconoPACK™ package. With a breakdown voltage of 1200V for a current of 100A, the module is optimized for high power converters and motor drivers. The power module integrates in a new generation of power packaging the improved IGBT4 and the optimized EMCON4 diodes from Infineon.
The EconoPACKTM IGBT4 offers a very low on-resistance (1.4 mΩ) and a higher operating temperature (up to 150 °C) in a 130.0 x 103.0 x 20.55 mm package. The IGBT4 differs from the IGBT3 for an adjusted backside, a different gate dimensions to obtain lower switching losses and increase softness for the same robustness.
This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost and selling price of the Infineon FS100R12PT4, a technological comparison between Infineon IGBT3 and IGBT4 and EconoPACK4 and HybridPACK2.
This report takes a look into the patenting activity around gallium Nitride uncovering the companies, inventors, and key applications.
GaN is a binary III-V direct bandgap semiconductor commonly used in LEDs. Its wide-band gap of 3.4 eV affords its special properties for applications in optoelectronic, high-power and high-frequency devices. Because GaN offers very high breakdown voltages, high electron mobility, and saturation velocity it is also an ideal candidate for high-power and high-temperature microwave applications like RF power amplifiers at microwave frequencies and high-voltage switching devices for power grids. Solutions that use GaN-based RF transistors are also replacing the magnetrons used in microwave ovens.
Gallium Nitride (GaN) transistor models have evolved from GaAs (gallium arsenide) transistor models; however there are many advantages GaN offers:
• Higher operating voltage (over 100-V breakdown)
• Higher operating temperature (over 150°C channel temperature)
• Higher power density (5 to 30 W/mm)
• Durable and crack-resistant material
GaN devices are often grown on SiC (silicon carbide) substrates, but to achieve lower-cost GaN devices, they can be grown on sapphire and silicon wafers. GaN’s wide bandgap allows for higher breakdown voltages and operation at high temperatures. The high thermal conductivity of SiC makes it a better substrate than silicon for power amplifier applications that require good heat sinking.

Power Electronics for EV/HEV 2016: Market, Innovations and Trends - 2016 Repo...Yole Developpement
The power electronics market for EV/HEV will reach $13B by 2021. Technology and business developments, as well as business opportunities, are expected in this growing industry.
The automotive market is turning electric
Sales of battery electric cars doubled between 2014 and 2015, an occurrence considered the first sign of the widespread acceptance of electrified cars. Pushed by aggressive targets in terms of CO2 emissions, electrification is undoubtedly the “greenest” option for car makers, with “diesel-gate” strengthening this impression and improving the public’s opinion of electric cars. The offer for electric and hybrid cars is growing by leaps and bounds, with premium car makers like Aston Martin and Jaguar also involved, and established car makers like General Motors launching affordable electric vehicles with sufficient range to be competitive with gas-powered vehicles. Once seen as a fancy-yet-flawed technology, electric cars are now becoming attractive thanks to players like Tesla and the financial benefits of owning an electric vehicle. The development of a charging infrastructure and an increasing range have also helped boost the market.
Considering all of these advantages, along with the political push for the mass adoption of electric cars, the market could be even higher. However, in order for electrified cars to enjoy global appeal some obstacles still must be cleared, such as charging regulations and the high sticker price compared to ICE vehicles.
In this report, you will find a detailed analysis of electrification’s pros and cons, as well as updated market metrics and forecasts for electric cars (by electrification type) and associated power electronics (inverter, power module, and power device). Market insights are also provided for the batteries used in electrified vehicles.

Status of the Power Electronics Industry - 2016 Report by Yole DeveloppementYole Developpement
With strong price pressure and a very strong leader, how will the power electronics market and landscape evolve in the future?
Vehicle hybridization is pulling the power electronics market
The 21st century is full of challenges to overcome, including population growth, reducing CO2 emissions and developing energy sources to replace liquid fuel. Power electronics will play a key part in solving these problems. Among the applications Yole Développement follows, motor drives are helping increase motor efficiency, photovoltaics and wind turbines continue expand their role in energy supply, and rail networks are moving more people. But one application stands out thanks to the huge volumes involved: electric vehicles. In the 2000s MOSFETs drove growth, and in the early 2010s it was renewable energy. The late 2010s and 2020s could be the golden era for electric vehicles, if customers adopt it and governments keep on subsidizing the field.
2015 has been a difficult year for the power electronics market, with the global value of power ICs, power modules and discrete components decreasing from $15.7 billion to $15.2 billion, a 3% drop. This fall is explained mainly by strong Average Selling Price (ASP) decreases at IGBT module level. We expect this ASP trend to continue, mainly because of price pressure from the automotive market. But overall IGBT module and global power electronics market value should increase, as volume growth outweighs this ASP fall. The automotive market will strengthen its position, as we expect electric and hybrid electric vehicles (EV/HEV) to represent a major part of the IGBT module market by 2021. Over this time the power MOSFET market is expected to grow slightly for all applications, going from $1 billion to $1.2 billion value.
The document discusses the construction and operating principles of an Insulated Gate Bipolar Transistor (IGBT). It describes how the IGBT was developed from earlier power semiconductor devices like the IGT and COMFET. The IGBT cell contains a parasitic thyristor structure that must be controlled to prevent latchup. In operation, the IGBT behaves like a MOSFET for gate control and can block high voltages while supporting medium frequencies and current levels, making it suitable for replacing bipolar junction transistors in applications like motor drives and power supplies.

Design of Low Cost Load Cell Amplification CardIRJET Journal
This document describes the design of a low-cost load cell amplification card. It begins with an abstract explaining that load cells produce low voltage signals that need amplification for measurement. The circuit uses three OP07 operational amplifiers to provide adjustable gain amplification of load cell signals from 0-20mV to -10V to +10V. Power is supplied by a voltage regulator circuit producing ±5V, ±12V, and 0V from a step-down transformer. PCB layouts are provided for the amplification card and power supply circuitry. The amplification gain can be adjusted using a 100k potentiometer to amplify low-level load cell signals for data acquisition.
Grids are already developing offshore, and this development will continue even though at what pace and how they will develop is still uncertain. Indeed, there are different possible configurations for a future offshore grid: it can be a simple multiplication of standalone lines that provide each a single service (either connection of generation, or connection between transmission grids); or it can be a more integrated infrastructure like an offshore meshed grid that combines and interconnects dozens of offshore lines and generation units (hereafter combined solution).

MATLAB/SIMULINK ANALYSIS OF A RIPPLE FREEHIGH EFFICIENCY BUCK-BOOST TYPE CONV...IRJET Journal
This document discusses the analysis and simulation of a ripple-free high-efficiency buck-boost converter for electric vehicle charging applications using MATLAB/Simulink. The converter uses a switched capacitor elevated phase inverted (SEPIC) topology which can boost or buck the input voltage to produce a regulated output voltage. Simulation results are presented for both open-loop and closed-loop operation of the converter. In open-loop simulation, the desired output voltage and current are not achieved due to lack of regulation. Closed-loop control will be needed to maintain regulation of the output voltage and current for electric vehicle charging applications.

The document presents a new bridgeless single-phase AC-DC converter based on a single-ended primary inductance converter (SEPIC) topology. The proposed rectifier utilizes a bidirectional switch and two fast diodes. It has less conduction losses compared to existing power factor correction rectifiers due to fewer components conducting during each switching cycle. Experimental results show the converter can achieve a high power factor under universal input voltage conditions and provide regulated output voltage for resistive and incandescent lamp loads. Future work may include further optimizing the design for applications requiring high power quality input power.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
