Mitsubishi Electric's Diode Modules

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.

End of year sale on Darrah’s GTO Gate Drives

Gate Drivers are designed for triggering large Gate-Turn-Off Thyristors (GTO) featuring gate-turn-off currents up to 3000 Amps and off-state voltages up to 4500 volts. The control signal, transmitted via fiber optics, controls the output valve of the gate driver. A feedback signal, also transmitted via fiber optics, is used to check that the gate driver and GTO are operating properly. This GTO Gate Driver was developed for use in traction systems and is currently being used successfully by numerous customers.
