Title:

MAGNETRON DRIVING POWER SUPPLY

Document Type and Number:

WIPO Patent Application WO/2006/126430

Kind Code:

A1

Abstract:

A magnetron driving power supply enabling stable inverter operation and having a good development efficiency. The difference between the emitter terminal potential (121) of a switching element (12) and the minus terminal potential (101) of a rectifying element (1) can be minimized, and stable switching and abnormal voltage detection are realized. The arrangement of the components of a magnetron driving power supply having a rated voltage range of 100 to 120V and that having a rated voltage range of 200 to 240V, particularly, the earth connection position (41) and the filament output position (42) are commonized, thereby providing a magnetron driving power supply having a good development efficiency thanks to, e.g., chassis standardization and best adaptable to the power supply voltage.
