Mitsubishi Electric offers general rectifying diode modules that rectify commercial frequencies and high frequency diode modules for freewheel diodes in inverter circuits and for high-speed switching on a surge voltage absorbing circuit (snubber).
The main switching devices of an inverter have changed from bipolar transistors to high-speed MOS gate devices, such as IGBT. The requirements of radio noise regulations have also increased the importance of not just reverse recovery characteristics, but also software recovery characteristics.
Main Applications
Inverter products/AC motor power supply/AC power supply for batteries/AC power supply for control boards/general AC power supply
Features
• Lineup includes modules with various types of connections
