Abstract
An electrical power supply is provided with a regulation stage which on being supplied at its input with a dc input voltage with a significant ripple component (V.sub.S1.sbsb.--.sub.OUT), outputs a dc output voltage (V.sub.S2.sbsb.--.sub.OUT) at a level substantially equal to the dc input voltage value at the troughs of the input ripple component (V.sub.T). As a result of this operation, the power dissipated in the stage is minimized. In order to regulate the dc output voltage (V.sub.S2.sbsb.--.sub.OUT) to be at a particular level, this output voltage is compared to a reference to produce a control signal (S) that is fed back to an upstream regulation stage. This upstream stage then serves to vary the level of the trough voltage at the input of the downstream regulation stage.
