Abstract

PURPOSE:To provide a difference between the positive and the negative pulse voltages to be supplied from a circuit by a method wherein a diode and a resistor which are connected in parallel, are added to the parallel circuit of an AC controlling element and a DC motive element. CONSTITUTION:An inverted wave-form is outputted from an inverter 8 and when the terminals A and C of a switch 9 are in an ON position, a signal is supplied to the base of a transistor 12, the transistor is turned to ON, a gate trigger current runs from the VPP of a DC stabilized power source 2 to the line of VSS passing through the terminal T1 of an AC controlling element 14, a gate G and the transistor 12, the AC controlling element 14 is conducted and a half-wave formed sine wave is supplied to the DC actuating element 15 through the intermediary of the diode 16. In like manner, when an ON position is given to the terminals B and C of the switch 9, the above is controlled by the inverted output signal of the inverter 8 and a negative half-wave formed sine wave which is divided from a resistor 17 is supplied to the DC motive element 15.
