Title:
CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2020/031553
Kind Code:
A1
Abstract:
This control circuit controls the driving of a MOSFET (350) equipped with a wide-gap semiconductor. The control circuit has an off-circuit (507) for discharging a charge stored in the gate electrode (350c) of the MOSFET to a reference voltage level. The off-circuit has: an off-resistor (553) and a first off-switch (554) which are provided in first wiring (540, 551) connecting the gate electrode and the reference voltage level; and a second off-switch (555) provided in second wiring (540, 552) connecting the gate electrode and the reference voltage level.
