Diode Modules
Outline
We offer 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
Diode modules decouple power supply units that are connected in parallel. Darrah offers diode modules ranging from 90 amps to 700 amps, and from 600 volts to 1800 volts.
