Title:
ELECTRIC POWER CONVERTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/105414
Kind Code:
A1
Abstract:
Disclosed is an electric power converting device with which drive control of a high-speed semiconductor switching element can be performed with high reliability. This electric power converting device is provided with a main circuit including a half-bridge conversion circuit, and a gate circuit for driving the half-bridge conversion circuit, wherein: arms (30H, 30L) forming the half-bridge conversion circuit include a pair of main terminals, and a control terminal to which a gate drive signal (GDS) for driving the semiconductor switching element contained in the arm is provided from the gate circuit; the gate circuit is connected between one of the pair of main terminals and the control terminal; and a clamp circuit in which a bidirectional switch (SWc) and a resistor (Rc) are connected in series is connected between one of the pair of main terminals and the control terminal.
