Abstract
A power regulator is provided which employs a resonant circuit and permits regulation between a certain maximum value and zero. A series resonant circuit is adjusted to regulate power by adjusting the correspondence between the resonance frequency and the frequency of the voltage source such as an AC source delivering a sine wave or a square wave. Further, the output voltage is regulated to be lower than the voltage of the AC source when output current is zero. A capacitance is connected in parallel with the output of the power regulator to form a second resonant circuit with the inductance of the series resonant circuit. A method of power regulation is also contemplated.
