Abstract
PURPOSE:To make envelope of load current perfectly flat, by reducing pulsating component through a control circuit then suppressing pulsating component perfectly through a pulsation suppressing circuit. CONSTITUTION:A power source circuit comprises a full-wave rectifier circuit DB, a switch element S, an inductance L1 for accumulating energy when the switch element S is turned ON, a capacitor C1 for charging when the switch element S is turned OFF, a control circuit 1 and a pulsation suppressing circuit 2, and feeds power to a load Z. The control circuit 1 controls ON duty of the switch element S1 such that voltage across the capacitor C1 is lowered for high output voltage from the full-wave rectifier circuit DB While it is increased for low output voltage from the circuit DB. Consequently, voltage having some what reduced pulsating component is applied onto the input terminal of the pulsation suppressing circuit 2 which suppresses output when input voltage increases and controls such that pulsating component of the input voltage is not applied onto a load Z.
