Intelligent Power Modules for Energy Efficiency, Reliability in Home Appliance Motors

Mon, 07/30/2007 - 12:45pm

ec78ps906a-LInfineon Technologies AG introduced a family of integrated intelligent power modules that contain nearly all of the semiconductor components required to drive electronically controlled variable-speed electric motors. The CiPoS (Control Integrated Power System) modules are designed to enable energy-efficient operation of consumer appliances such as washing machines and air conditioners, offering efficiencies of up to 94 percent. The modules incorporate a three-phase inverter power stage with a SOI (Silicon-On-Insulator) gate driver, boot strap diodes and capacitors, and auxiliary circuitry in a compact, fully isolated package. Based on a combination of the company’s TrenchStop IGBT (Insulated Gate Bipolar Transistor) and EmCon (Emitter Controlled) diode technology, they are said to eliminate as many as 23 discrete components compared to a design based on discrete components. With a basic drive system, such as used in a fan blower, only requiring nine external components and one microcontroller, the CiPoS modules are ready-to-use for all motor drive systems with a power rating of up to 3 kW. The CiPoS modules also a low junction-to-case resistance, which according to the company, increases output current by up to 20 percent compared to other available modules.
