Power converter with voltage drive switching device monitored by device parameters and electric parameters

摘要

A power converter having at least a pair of voltage drive switching elements, which comprises a gate control circuit, the gate control circuit comprising a detecting section for detecting at least one of a set of device parameters and a set of electric parameters of the voltage drive switching elements, a monitoring section for monitoring at least one of states of turn-on and turn-off of the voltage drive switching elements based on the at least one of a set of device parameters and a set of electric parameters of the voltage drive switching elements detected by the detecting section, and a control section for controlling a gate of the voltage drive switching elements based on a monitoring result of the monitoring section.
