Abstract

PURPOSE:To make a current which is supplied from a power source nearly sinusoidal wave by supplying the current of a power source cylce controlled at its conducting phase angle by the first device during nonconducting period to the second load. CONSTITUTION:When a power source 1 is thrown, a capacito 13 is charged by the voltage across a zener diode 8. When the charged voltage reaches the gate voltage of a PUT11, the first switching element 16 is conducted by a pulse which is generated at the secondary side of a pulse transformer upon discharging of the capacitor, allowing a voltage (e) to be supplied to the first load 17. On the other hand, the voltage before the charged voltage reaches the gate voltage of the PUT11 is supplied through a resistor 24 to an amplifier 21, the output of the amplifier permits a light emitting element 26 to emit a light, thereby conducting the second switching element, allowing a voltage (g) to be applied to the second load 29. In this manner, nearly sinusoidal current can be supplied from the power source 1.
