Abstract
PURPOSE:To make the title voltage detector an inexpensive one, by constituting a voltage detection circuit taking advantage of the output voltage of a DC/DC converter. CONSTITUTION:An inverter is composed of a DC power source 1 and transistor modules 2 and feeds the current to a load 3. It is also equipped with a DC/DC converter 4 and a control circuit 6, with which the above modules 2 are controlled. On this occasion, in place of an insulating amplifier a voltage detection circuit 7 is juxtaposed and connected between the DC/DC converter 4 and the control circuit 6. In this detection circuit 7 let the secondary side winding voltage be the voltage detected, because it is proportional to the primary side input voltage in accordance with the turn ratio of each winding when the switching transistors of a flyback type DC/DC converter 4 are turned ON.
