Abstract

PURPOSE: To prevent elements easily and certainly from being damaged by providing either a normal mode choke coil or a common mode choke coil on a control signal output side of a gate drive circuit for high-speed switching semiconductor elements.
CONSTITUTION: A gate drive circuit 9 is composed of a photocoupler 3, transistors(Tr) 4-6 and DC control power devices 7-8. With a switch 1 turned ON across its terminals C-B an FET is caused to be in an ON state, while the FET is set to work in an OFF state when terminals A and C are connected to switch ON. In this connection, normal mode choke coils 10 and 11 and a common mode choke coil 12 are provided. Thus, the control signal output terminals G and S of the gate drive circuit 9 are connected respectively to a gate terminal G and a source terminal S of the FET through the above choke coils 10-12 and the induced voltage or charge current caused by the sudden potential fluctuation in switching can be prevented from running into the above gate drive circuit 9.
