Mitsubishi Electric launches SiC power semiconductor modules at PCIM 2013



Mitsubishi Electric announced the launch of three types of silicon carbide (SiC) power modules for home appliances, industrial equipment and railcar traction systems. The modules, which use schottky-barrier diodes (SBD) made with SiC, are expected to reduce the size, lower the weight and raise the efficiency of inverters in power electronics devices. The hybrid SiC DIPPFCTM* for home appliances and hybrid SiC modules for railcar traction system will be exhibited at Power Conversion Intelligent Motion (PCIM) Europe 2013, which will be held in Nuremberg, Germany from May 14 to 16. *DIPPFC: Transfer-mold-type IPM with for power-factor correction (PFC) circuits. In recent years, inverters have come to be used in a wide variety of applications, including home appliances such as air conditioners and refrigerators, as well as industrial equipment and railcar traction systems. Power semiconductors utilizing SiC can dramatically decrease power loss and enable high-speed switching, which is raising expectations from the point of view of energy efficiency. Product Features 1) Hybrid SiC DIPPFCTM for home appliances - SiC-SBDs reduce recovery current and decrease electromagnetic interference noise - Realizes high-frequency switching of up to 30kHz, and contributes to the downsizing of reactors - PFC circuit and drive IC reduces footprint and simplifies wiring pattern - Package dimensions compatible with Mitsubishi Electric's supermini DIPIPMTM products 2) Hybrid SiC-IPM for general industry - Diodes made with advanced SiC-SBD - Reduces power loss by about 20% compared to Mitsubishi Electric's PM200CS1D060 (S1-IPM) and enables smaller, more efficient equipment - Package and control terminals compatible with Mitsubishi Electric's PM200CS1D060 (S1-IPM) - Same protections as those in Mitsubishi Electric's PM200CS1D060 (S1-IPM) 3) Hybrid SiC modules for traction systems - Diodes made with advanced SiC-SBD - Reduces power loss by about 30% compared to Mitsubishi Electric's CM1200DC-34N (N-series IGBT) and enables more efficient devices - Package and terminals compatible with Mitsubishi Electric's CM1200DC-34N (N-series IGBT) - High reliability suitable for use in traction systems
