IGBT/MOSFET Gate Drive Optocoupler
www.vishay.comThe Insulated Gate Bipolar transistor (IGBT) is a cross between a MOSFET (metal oxide semiconductor field effect transistor) and a BJT (bipolar junction transistor) since it combines the positive aspects of MOSFETs and BJTs. The IGBT has …

The filter section, primarily a capacitor bank, is used to smooth out the DC voltage that is produced from the converter section. A link choke or inductor can be added to improve power factor and reduce harmonics.
