摘要:
A magnetron feeding apparatus and a method of controlling the magnetron feeding apparatus having an inverter circuit for converting the DC power supply into high-frequency power, a high-tension transformer for converting the high-frequency power into the high-tension power to be applied upon the magnetron, an output voltage detecting portion for detecting the output voltage of the high-tension transformer, an input current detecting portion for detecting the input current into the inverter circuit, a power controlling means for controlling the operation of the inverter circuit by the output voltage information of the output voltage detecting portion and the input current information of the input current detecting portion.
摘要:
A high-frequency heating apparatus comprises a semiconductor power converter (33) which is supplied with electric power from a commercial power supply, etc., a radio wave radiation section (32) which is energized by the semiconductor power converter (33), a control section (34) which controls the operation of a semiconductor element (28) of the semiconductor power converter (33), and a start control section (41) which controls the operation of the control section (34) at the start time of the high-frequency heating apparatus. The start control section (41) controls the operation of the control section (34) so that the radio wave output power from the radio wave radiation section (32) at the start time of the high-frequency heating apparatus becomes greater than that in the steady operation state thereof, whereby the optimization of the performance and price of the heating apparatus can be realized.
