Abstract
A d-c power supply is described which is energized from a relatively low frequency power source and produces a d-c output voltage with low ripple and high power factor. An inductance-capacitance circuit is connected in series with the a-c source and the a-c side of the rectifying element. A filter capacitor is connected to the d-c side of the rectifying element. The inductance-capacitance circuit resonates at a frequency of about three to six times the frequency of the input power supply. A plurality of circuits for carrying out the invention are disclosed.
