A voltage regulator generates an output voltage between an output line and an output reference voltage from an input voltage between an input line and an input reference voltage. The voltage regulator combines a self excited series resonant oscillator and a switching regulator control circuit. The self excited series resonant oscillator includes an oscillator circuit which produces an oscillating signal. The oscillating signal is rectified to produce a rectified signal. The rectified signal is filtered to produce the output voltage on the output line. The switching regulator control circuit switches the self excited series resonant oscillator on and off at a duty cycle which maintains the output voltage on the output line at a predetermined value.
