Circuit arrangement for controlling electronic power converter, has transistor generating driving signal for driving electrode, where switching-on of transistor is blocked when transistor drives current in reverse direction

摘要

The arrangement has a reverse conducting insulated gate bipolar transistor driving load current in forward and reverse directions, and a gate electrode switching on and off the transistor. A control signal representing switching status of the transistor is input to a trigger circuit. The transistor is designed to generate a driving signal for driving the gate electrode to the transistor according to switch on-off of the control signal. Switching-on of the transistor is blocked when the transistor drives the current in reverse direction. An independent claim is also included for a method for controlling a reverse conducting insulated gate bipolar transistor.
