Silicon Carbide (SiC) Increasing Use In Power Electronic Devices
by MWilliams | 26 June 2017 | Latest News & Information
Since the early sixties, Silicon has been used as a semiconductor “switch” and the quest for higher switching frequencies, greater power densities, higher blocking voltages, lower losses, increased operating temperatures etc. has led to the introduction of Silicon Carbide (SiC) and other wide band gap materials in power devices.

SNUBBER & MOV CIRCUITS FOR THYRISTOR ASSEMBLIES
by MWilliams | 12 June 2017 | Latest News & Information
What are snubber & MOV circuits for?
Snubber circuits are used to control voltage transients that could falsely turn on or damage a thyristor. The object of the snubber is to suppress the voltage transients and ringing that occurs when the thyristor is switched by providing an alternate path for the current flowing through the circuit’s
