Abstract
A power conversion device includes a power semiconductor switch module, a driving signal-transmitting circuit, a plurality of failure-detecting circuits, a protection signal transmitting circuit and a control circuit. The driving signal transmitting circuit receives a control signal and generates a driving signal according to the control signal to drive the power semiconductor switch module. The failure detecting circuits generate a fault signal when they detect that one of the power semiconductor switches and/or the driving signal transmitting circuit is malfunctioning. The isolated pulse transforming unit of the protection signal transmitting circuit receives a corresponding fault pulse signal generated according to the fault signal, and outputs a protection pulse signal. The control circuit generates the control signal and receives a protection signal generated according to the protection pulse signal. The control circuit generates a turn off signal according to the protection signal to turn off the power semiconductor switch module.
