Editor's Notes
- Welcome to the training module on Intelligent Power Modules for Motion Control . This training module introduces the intelligent power modules, their key features and product portfolio.
- From industrial control to automotive electronics, home appliances to lighting, telecommunications and networking to the latest audio equipment, modern electronic applications share a common design requirement – the need for the efficient control and conversion of power. Alternating current (AC) induction motors are the workhorses behind these applications. Traditionally, these motors have been run with fixed speed control, which is not the most efficient. Variable speed drives are key to high performance, efficient and cost-effective motion control solutions that minimize noise and enhance reliability. Power modules for inverterized motor drive applications, are a current trend, due to the advantages they present like space saving and ease of assembly. International Rectifier’s intelligent power module or IPM series has been developed for appliance applications, which addresses these factors. It enables the integration of 3 phase motor drives used in a variety of appliances, such as washing machines, energy efficient refrigerators and air conditioning compressor drives in 200W to 5000W power ranges.
- The intelligent power module is a complete integrated solution. Replacing more than 20 discrete parts, IR’s IPMs in SIP packaging reduce component count and board space whiles improving reliability by delivering a complete power stage for variable speed motors. The IPM contains six IGBT dies, each with its own discrete gate resistor, six commutation diode dies, one 3-phase monolithic, level shifting driver chip, three bootstrap diodes with a current limiting resistor and an NTC thermistor or resistor pair for over-temperature protection. All these components are mounted on Insulated Metal Substrate , which was originally developed as a low cost method for mounting bare chips and has evolved into an excellent technology for achieving high performance and high reliability in high-density solutions.
- The performance of the IPM in a system depends on many application-related parameters, such as the switching frequency and phase current. In order to choose the right IPM, the engineer starts with information about the application. For example, consider a washing machine controller intended for operation at up to 3 amp rms phase current and 16 kHz switching frequency. The phase current means that a specific power module can deliver to the motor in specific application conditions. The maximum current is the current that will cause the junction temperature to reach the maximum allowed, like 150 ºC. Knowing the switching frequency in the application, the power losses can be averaged per switching cycle i.e power loss per switch cycle. IR’s datasheets provide some guidance, but they are usually related to certain operating conditions.
- The current capability can be given as a function of switching frequency, as shown in the chart. These curves show the influence of the switching losses.
- This table lists the products in IPM family with the key specifications.
- The SIP-S modules are developed for low power appliance motor control applications such as Fans, Pumps, refrigerator compressors and so on. The compact Single in line (SIP-S) package minimizes PCB space. The MOSFET blocking voltage is 500V. At 20kHz switching frequency, the maximum output phase RMS current reaches 1A.
- The IRAM109 contains two low power H-bridge HVIC drivers or IR2109. The IR2109 is a high voltage, high speed power MOSFET and IGBT drivers with independent high & low side referenced output channels. The output drivers feature a high pulse current buffer stage, designed for single phase motors, DC motors, Bi-directional control, fans, pumps and compressors.
- These curves shows the output phase current as a function of switching frequency for the IR2109 .
- The IRAM336-025SB integrates a low power 3-phase HVIC driver or IRS2336D. The IRS2336D 3 phase gate driver with integrated bootstrap functionality is designed for appliance motor control, servo drives, micro-inverter drives, and a wide range of general purpose applications, such as fans , compressors and pumps.
- The curves shows the output phase current as a function of switching frequency for the IRS2336D .
- The IRAM136-3023B is a 30A, 150V integrated power hybrid IC with fully protected functions for low voltage motor-drive applications and battery operated motor control applications, such as electric vehicles and portable power tools. The IRAM136-3063B is a 30A, 600V Integrated Power Hybrid IC ideal for mains operated motor control applications, such as air conditioning systems and compressor drivers as well as for light industrial application. Both devices contain a 3-phase high voltage, high speed driver in a fully isolated thermally enhanced package. A built-in temperature monitor, over-current & over-temperature protections, together with integrated under-voltage lockout function, deliver high level of protection and fail-safe operation.
- Here is the block diagram of the IRAM136-3063B. The 600V Plug N Drive module contains six IGBT dies, each with its own discrete gate resistor, six commutation diode dies, one 3-phase monolithic, level shifting driver chip, three bootstrap diodes with a current limiting resistor and an NTC thermistor or resistor pair for over-temperature protection. The over current trip circuit also responds to an input signal generated from an external sense element such as a current transformer or sense resistor. The input pin for the trip circuit, performs a dual function, as an input pin for over current trip voltage and an output pin for the module’s analog temperature sensing thermistor. Using a new developed single inline package with heat spreader for the power die along with the full transfer mold structure, minimizes PCB space and resolves isolation problems to heatsink.
- Here is the block diagram of IRAM136-3023B. This advanced HVIC, is a combination of IR's low RDS(on) Advance Planar MOSFET Super Rugged technology and the industry benchmark 3-Phase high voltage, high speed driver in a fully isolated thermally enhanced package. Using a new developed single in line package (SiP3) with heat spreader for the power die along with the full transfer mold structure, minimizes PCB space and resolves isolation problems to heatsink.
