RESONANCE FREQUENCY TUNING APPARATUS OF A INVERTER TRANSFORMER

摘要

A resonance frequency tuning apparatus of an inverter transformer is provided to maximize energy conversion from a primary part to a secondary part of the inverter transformer by varying a resonance frequency stably between a load and the inverter transformer. An inverter transformer includes a resonance condenser(Cr), a ballast capacitor(Cp) and a transformer having a primary coil(L1) and a secondary coil(L2). An external static magnetic field generation apparatus(10) performs variable control of a resonance frequency of the transformer(TRANS) by forming an external static magnetic field. A manual driving apparatus(20) makes the external static magnetic field generation apparatus approach the transformer of the inverter transformer or be separated from the transformer by being operated manually.
