PROBLEM TO BE SOLVED: To acquire a high voltage DC output by a simple constitution. SOLUTION: Push-side and pull-side electric field effect transistors connected to positive and negative high voltage power sources via push-side and pull-side photocouplers are driven by amplification voltage outputs of input arithmetic amplifier circuits for amplifying voltage inputs. Consequently, a processing circuit connected to the high voltage power source is simplified, and high output DC amplifier circuits with excellent pressure-proof characteristics are acquired.
