The document discusses the vacuum pressure impregnation (VPI) process for insulating the windings of large electric machines like turbo generators. It describes how VPI eliminates air gaps in windings to reduce hot spots and lower operating temperatures. VPI seals the machine against environmental conditions and bonds insulation components for strength. This reduces noise and increases the dielectric capability of the machine. The document reviews the existing VPI system and materials used, including resins, tapes and the heating/cooling cycle. It provides details on mixing resins and the sizes of tanks used in the VPI process.
Electromechanical energy conversion principlesVijay Raskar
This document contains a summary of the key concepts from the chapter "ELECTROMECHANICAL CONVERSION PRINCIPLES" in the textbook "ELECTRICAL MACHINES". It explains that electromechanical systems convert energy between electrical and mechanical forms by using magnetic and electric fields to store energy. Electromechanical devices can produce small motions, forces, or continuous energy conversion as in motors and generators. The magnetic field has much greater energy storage capacity than the electric field. The principle of energy conversion states that energy cannot be created or destroyed, only converted between different forms.

This document discusses the challenges for materials used in electric motors as the demands of electric vehicles increase. It notes trends toward higher power, torque, and voltage as well as increased motor speeds. These trends place new demands on motor materials, including the need for insulation that can withstand higher voltages and temperatures. Electrical steel must reduce losses at higher frequencies while maintaining strength. Permanent magnets must operate at higher temperatures while providing increased flux. The document argues that cooperation between motor and material suppliers will be important to develop new materials that allow improvements in motor design and help accelerate electric vehicle adoption.
GaN-on-Si Substrate Technology and Market for LED and Power ElectronicsYole Developpement
GaN-on-Si enables GaN power electronics, will LED transition as well?
GaN-ON-Si LED IS ALREADY ADOPTED BY SOME LED MANUFACTURERS, BUT COULD IT BECOME THE INDUSTRY STANDARD?
Today, GaN on Sapphire is the main stream technology for LED manufacturing. GaN-on-Si technology appeared naturally as an alternative to sapphire to reduce cost. Our cost simulation indicates that the differential in silicon substrate cost is not enough to justify the transition to GaN-on-Si technology. The main driver is the ability to manufacture in existing, depreciated CMOS fabs in 6” or 8”.
Despite potential cost benefits for LEDs, the mass adoption of GaN-on-Si technology for LED applications remains unclear. Opinions regarding the chance of success for LED-on-Si vary widely in the LED industry from unconditional enthusiasm to unjustified skepticism. Virtually all major LED makers are researching GaN-on-Si LED, but few have made it the core of their strategy and technology roadmap. Among the proponents, only Lattice Power, Plessey and Toshiba have moved to production and are offering commercial LED-on-Si.
At Yole Développement, we believe that although significant improvements have been achieved, there are still some technology hurdles (performance, yields, CMOS compatibility). We consider that if the technology hurdles are cleared, GaN-on-Si LEDs will be adopted by some LED manufacturers, but will not become the industry standard. We expect that Silicon will capture less than 5% of LED manufacturing by 2020.
GaN-ON-Si TECHNOLOGY WILL BE WIDELY ADOPTED BY POWER ELECTRONICS APPLICATIONS
The power electronics market addresses applications such as AC to DC or DC to AC conversion, which is always associated with substantial energy losses that increase with higher power and operating frequencies. Incumbent silicon based technology is reaching its limit and it is difficult to meet higher requirements. GaN based power electronics have the potential to significantly improve efficiency at both high power and frequencies while reducing device complexity and weight. Power GaN are therefore emerging as a substitution to the silicon based technology. Today, Power GaN remains at its early stage and presents only a tiny part of power electronics market.
We are quite optimistic about the adoption of GaN-on-Si technology for Power GaN devices. GaN-on-Si technology have brought to market the first GaN devices. Contrary to the LED industry, where GaN-on-Sapphire technology is main stream and presents a challenging target, GaN-on-Si will dominate the GaN based power electronics market because of its lower cost and CMOS compatibility. Although GaN based devices remain more expensive than Si based devices today, the overall cost of GaN devices for some applications are expected to be lower than Si devices three years from now, according to some manufacturers.

Simplified svpwm algorithm for neutral point clamped 3 level inverter fed dtc...Asoka Technologies
In this paper, a simplified space vector pulse width modulation (SVPWM) method has been developed for three phase three-level voltage source inverter fed to direct torque controlled (DTC) induction motor drive. The space vector diagram of three-level inverter is simplified into two-level inverter. So the selection of switching sequences is done as conventional two-level SVPWM method.Where in conventional direct torque control (CDTC), the stator flux and torque are directly controlled by the selection of optimal switching modes. The selection is made to restrict the flux and torque errors in corresponding hysteresis bands. In spite of its fast torque response, it has more flux, torque and current ripples in steady state. To overcome the ripples in steady state, a space vector based pulse width modulation (SVPWM) methodology is proposed in this paper. The proposed SVPWM method reduces the computational burden and reduces the total harmonic distortion compared with 2-level one and the conventional one also. To strengthen the voice simulation is carried out and the corresponding results are presented.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
