Title:
DRIVING CIRCUIT AND ELECTRIC POWER CONVERSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/032354
Kind Code:
A1
Abstract:
Provided are a driving circuit capable of driving a CG-IGBT collector gate with the same PWM signals as a common IGBT using a low-cost structure, and an electric power apparatus provided with said driving circuit. This driving circuit drives a collector gate control IGBT provided with an emitter, a collector, an emitter gate on the emitter side, and a collector gate on the collector side, and has a first gate driver for driving the gate on the emitter side and a second gate driver for driving the gate on the collector side, wherein the same driving command signal is input into the first gate driver and the second gate driver, and the second gate driver has a high breakdown voltage diode into which is input a signal based on the driving command signal.
