Abstract

PURPOSE:To operate a load effectively in AC and DC power supply by providing a connection line for DC power supply to a connecting point between a 1st constant voltage circuit and a 2nd voltage circuit. CONSTITUTION:An input terminal of a rectifier 1 is connected to an AC power supply 3 via an AC load 2 and the 1st constant voltage circuit 4 is connected to the output terminal. A detection circuit 15 detecting an object 14 to be detected is connected to the input terminal of a switch circuit 15 and a switching element 21 is connected to the output terminal and the 2nd constant voltage circuit 23 is formed while the constant voltage diode 22 is connected in parallel. The connecting point between the 1st constant voltage circuit 4 and the 2nd constant voltage circuit 23 connects to a connection line 25 and the terminal A of the connection line 25 is connected to a DC power supply 27 via a DC load 26. Thus, the remaining voltage at the ON-state of the switch circuit in common use with a DC can drive sufficiently the DC load.
