    摘要： This invention provides a power converter system comprising; switching devices for connecting d.c. and a.c voltage terminals, a pulse generator (200,500) for generating signals to drive said switching devices, drive circuits to drive said switching devices in response to driving signals from said signal generator, and a transmission circuit for interconnecting said drive circuits, wherein the delay time for the drive circuit to turn off the switching device after receiving an OFF signal is greater than the delay time for the drive circuit to turn on the switching device after receiving an ON signal.
    A high reliability power converter system that assures prevention of arm short circuit is realized.
