Abstract

PURPOSE:To protect an inverter from surge and the like, by short-circuiting at least one of input and output windings of a drive transformer when input of overvoltage from a DC power source is detected. CONSTITUTION:An inverter comprises switching devices 1, 2 having control electrodes and a DC power source 3 and feeds power to the load 5 of an output circuit 5. The switching devices 1, 2 are driven by a control circuit 6 through a drive transformer 7. An overvoltage detector 8 comprising a constant voltage element 81 and the like and a shortcircuit 9 for short-circuiting the input winding of the transformer 7 corresponding to a signal fed from the overvoltage detector 8 are provided. Upon provision of overvoltage from the DC power source 3, a transistor 93 in the short-circuit 9 is turned ON to short-circuit an input winding 71 so as to turn the switching devices 1, 2 forcibly. Consequently, the switching devices 1, 2 can be protected from overvoltage.
