MAGNETRON DRIVE APPARATUS

摘要

In a magnetron drive apparatus, a high frequency voltage converted and output by a frequency converter is input to a primary winding of a transformer and a high voltage power output from a secondary winding of the transformer is rectified and supplied to an anode of the magnetron and power output from a heater winding of the transformer is supplied to a heater of the magnetron. The magnetron drive apparatus comprises a magnetic flux leakage device disposed in a magnetic path formed by the primary and secondary windings of the transformer and increases a leakage magnetic flux in the magnetic path. A device around which the secondary winding and the heater winding are wound is provided at a position opposite the primary winding, with the magnetic flux leakage device arranged therebetween.
