Abstract
A switching element, a transformer having a primary winding connected through said switching element to a DC power supply and a resonance capacitor connected in parallel with the primary winding of said transformer constitute a single-ended switching circuit. A magnetic amplifier is connected between the secondary side circuit of the transformer of the single-ended switching circuit and a rectifying/smoothing circuit, thus forming a high frequency switching circuit.
Claims5
A high frequency switching circuit comprising:
- a single-ended switching circuit including a transformer having a primary winding and a secondary side circuit, a switching element circuit connected between the primary winding of said transformer and a DC power supply and a resonance capacitor connected in parallel with said primary winding;
- a rectifying/smoothing circuit including a filtering capacitor connected in parallel with a rectifying element and a load;
- and
- a magnetic amplifier connected between said secondary side circuit of said transformer and said rectifying/smoothing circuit.
