Abstract
A rectifying and smoothing circuit comprises a first rectifier for rectifying an input signal voltage, a first smoothing circuit for smoothing the output voltage of the first rectifier, an attenuation circuit for attenuating the output voltage of the first smoothing circuit, a second rectifier for rectifying voltage passing through the attenuation circuit, a second smoothing circuit for smoothing the output voltage of the second rectifier, and a feedback circuit for feeding back the output voltage of the second smoothing circuit to the first smoothing circuit, the second smoothing circuit, after being charged at a specific voltage, is held at said charging voltage until the output voltage of the first smoothing circuit becomes less than the output voltage of the second smoothing circuit, the output voltage of the second smoothing circuit being derived as the output of the rectifying and smoothing circuit.
