Abstract
The drive circuit for driving voltage controlled switches includes: charge path connected to gate of the switch, through which gate charge current flows to turn the switch ON; discharge path connected to the gate and output terminal of the switch, through which gate discharge current flows to turn the switch OFF; and at least either, a charging side element disposed on charging side loop path having the gate, a part of the charge path and the output terminal, restricting current flow to be in one direction and not disturbing current flow of charge current; or a discharging side element disposed on a discharging side loop path having the gate, a part of the discharge path and the output terminal, restricting a current flow to be in one direction and not disturbing a current flow of discharge current.
