Abstract
A series resonant circuit includes a series connected power source, inductor and capacitance. The resonant capacitance includes two separate capacitors, connected to form a voltage doubler. Two rectifiers clamp the resonant capacitors' voltage to the output voltage, so the voltage on the resonant capacitors is limited under overload conditions. Current control may be achieved by modulation of the power source frequency.
