ABSTRACT:
A power control circuit is disclosed which may comprise a transformer having a primary winding and at least one secondary winding, a first and a second series circuit, and a rectifier circuit. The first series circuit may include a first DC power source, a first transistor and the primary winding of the transformer. The second series circuit may include the primary winding of the transformer, an excitation coil arranged to flow through the primary winding of the transformer a current which increases with time, a second DC power source and a second transistor. The rectifier circuit may be connected with the secondary winding of the transformer. In this power control circuit, an excitation current is first caused to flow through the primary winding of the transformer so that energy is stored therein. Thereafter, a current opposite to the excitation current is caused to flow through the primary winding of the transformer, and a current induced from the current flowing from the secondary winding to the primary winding of the transformer and a current resulting from the energy stored in the primary winding of the transformer are superimposed upon each other in the secondary winding of the transformer. Finally, a current resulting from the superimposition is rectified by the rectifier circuit, so that a continuous output is provided.
