Document Type and Number:
WIPO Patent Application WO/1992/002111
Kind Code:
A1
Abstract:
The equipment includes a DC power supply comprising a power generator (20), an electric power generator (22) and a rectifying means (23), an inverter power supply (24) which boosts the output voltage of the DC power supply and drives a magnetron (28), and an inverter controlling part for controlling the inverter power supply (24) according to the output of a generator output detecting means (31) for detecting the output of the DC power supply. A function of dielectric heating can be exhibited stably by controlling the operating state of the inverter power supply (24) through the use of the output of the DC power supply.
