SEMI-CONDUCTOR DEVICE SIGNAL TRANSMISSION CIRCUIT FOR DRIVE CONTROL, METHOD FOR CONTROLLING SUCH A CIRCUIT, SEMICONDUCTOR DEVICE, POWER CONVERSION DEVICE AND ELECTRICAL SYSTEM FOR RAIL VEHICLES

摘要

Providing a semiconductor device signal transmission circuit for drive control, a method of controlling a semiconductor device signal transmission circuit for drive control, a semiconductor device, a power conversion device and an electrical system for a rail vehicle, which is capable of preventing malfunction due to disturbance and at the same time speeding up a switching operation or its loss to reduce. The semiconductor device signal transmission circuit for drive control connected between a semiconductor device forming an arm in a power conversion device and a drive circuit configured to drive the semiconductor device includes: an inductor; and an impedance circuit including a switch and connected in parallel with the inductor.
