Title: Resonance inverter
Inventor: SCHUTTEN MICHAEL J
IPC: H02M3/337
Filed: 2002-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a resonance inverter control wherein an output load voltage is kept substantially constant in every load state. SOLUTION: When an operation is performed within a frequency range in which a controllable switch means is operable, a rectangular-wave voltage applied to a series resonance circuit is subjected to a frequency modulation, and thereby constant an output voltage is supplied and a stable operation is maintained. At the margin of a frequency range in which the controllable switch means is operable, a phase modulation angle corresponding to a desired output voltage is calculated, and a phase shift control signal representing the phase modulation angle is generated. A wider dynamic range of the output load voltage can be attained in every operating state by combining an optimum control method with a phase modulation, in this way.
