摘要： A power supply for a magnetron includes a rectifying circuit, a switching circuit, and a transformer. The rectifying circuit converts an ac-power source signal into a dc-power source signal. The switching circuit converts the dc-power source signal output from the rectifying circuit into a high-frequency signal in accordance with a driving circuit. A transformer connected to the switching circuit converts the high-frequency signal into a high-voltage high-frequency signal for driving the magnetron. The transformer includes a primary winding connected to the switching circuit, a secondary winding connected to the magnetron, a tertiary winding connected to a cathode heater of said magnetron, and a fourth winding connected to the driving circuit. The coupling coefficient between the fourth winding and the second winding is larger than the coupling coefficient between the fourth winding and the primary winding.

摘要： A high-frequency heating apparatus comprises an inverter including a semiconductor switch and a resonance capacitor, a boosting transformer for a supplying high-voltage power and heater to a magnetron an inductance device inserted in the heater circuit of the magnetron, and an inverter control unit for controlling the semiconductor switch. The inverter control unit is controlled by a start control at the start time of the inverter so that the conduction time of the semiconductor switch becomes shorter than that under a normal operating condition and the non-conduction time thereof becomes longer than that under a normal operating condition and so that the switching period of the semiconductor switch becomes substantially an integral multiple of a resonance period of the resonance circuit formed by the resonance capacitor, whereby the operating frequency of the inverter at the time of starting thereof becomes substantially equal to its normal operating frequency.

摘要： A high-frequency heating apparatus comprises a power supply including a commercial power supply or a battery, a frequency converter for converting the power of the power supply into high-frequency power, a boosting transformer for increasing the voltage of the output of the frequency converter, and a magnetron for receiving the output from the boosting transformer. The apparatus further comprises a shield member made of a non-magnetic conductive material and forming a substantially electrical open loop in the winding direction of the primary winding between the primary and secondary windings of the boosting transformer. The shield member is connected to the core or the housing of the boosting transformer thereby substantially containing a high-voltage circuit in the shield space. High safety of the high-frequency heating apparatus is thus assured without grounding the housing.

摘要： A high-frequency heating device includes a power converter for converting an electric power from a commercial power source or the like into a high-frequency power, a step-up transformer having a high-voltage winding and a low-voltage winding, a magnetron receiving high-voltage and low-voltage outputs, a resonance circuit connected in series or parallel with the filament of the magnetron, and a control circuit. The control circuit controls the power converter so that the operation frequency of the power converter approximately coincides with the resonance frequency of the resonance circuit at the time of activating the power converter to thereby achieve a rapid start of the oscillation operation of the magnetron while suppressing a high voltage from taking place at the activation time to prevent the possible occurrence of the moding phenomenon.
