Abstract
An LC resonant circuit. The resonant circuit includes a resonant capacitor and a transformer. The transformer comprises a magnetic core having a primary winding, secondary winding and control winding wound on the core. The primary winding is loosely coupled with the secondary winding. The resonant capacitor of the circuit is connected in series with the primary winding of the transformer. The control winding saturates the core in response to the application of direct current thereto to control the output of the resonant circuit.
