摘要： A microwave oven having a cabinet, a door, a programming interface, a magnetron tube that capable of being dynamically controlled, a controller configured to control the magnetron tube, and a microwave generating system is described. A method of dynamically controlling the magnetron tube in the microwave oven by utilizing a magnetron power supply is also described. By monitoring a current to the magnetron power supply, determining the current to the magnetron power supply at which the magnetron tube conducts, calculating a time base, and adjusting the time base as the power level required is increased, the control produces consistent power when the magnetron tube is cycled at less than a 100% power level and to compensate for a slow start of the magnetron tube during a short cook cycle.

The power converter includes a switching unit to perform switching using a direct current (DC) voltage and to output an alternating current (AC) voltage, a driving unit to output a high-frequency voltage to a magnetron based on the AC voltage, an output voltage detector to detect an output voltage flowing to the magnetron, and a controller to calculate a frequency command value based on the detected output voltage, to generate a frequency command value by avoiding a resonance frequency when the calculated frequency command value corresponds to the resonance frequency, and to output the generated frequency command value to the switching unit. Therefore, it is possible to stably perform oscillation.

摘要： An inverter controller controls an inverter. The inverter converts direct current into alternating current of a predetermined frequency. The inverter includes a resonance circuit for fluctuating output of a predetermined object to be controlled. The inverter controller comprises an output fluctuating unit which fluctuates output of the inverter in response to an output value of a temperature detection section which detects a temperature of a switching element of the inverter. The inverter controller further comprises an output increase suppressing unit which suppresses an increase in the output of the inverter for a predetermined time after decrease control in the output of the inverter performed by the output fluctuating unit.

摘要： To attain a more reliable prevention of an electric shock by checking whether the earth states for two circuit boards are good. There is detected a voltage generated at an anode current sensing resistor 20 inserted into a path where the anode current of a magnetron 8 flows and a signal is transmitted to a microcomputer 27. The microcomputer 27 uses a selector switch 28 to determine the earth states for an inverter circuit board and a control panel circuit board before operation of a device. In case either one or both of the circuit boards are in a floating state, operation of a high-frequency heating device is inhibited. Otherwise, operation of the high-frequency heating device is permitted.

摘要： A power supply for a magnetron varies a power output level and prevents moding of the magnetron. To provide a variable power output, a microprocessor senses an anode current and voltage of the magnetron. Based on the sensed signals, the microprocessor adjusts the conduction angle of a thyristor to obtain the desired power level. The microprocessor also monitors the anode voltage for detecting moding of the magnetron. If moding is detected, the microprocessor adjusts the conduction angle of another thyristor to change the current supplied to the filament. By changing the filament current, the microprocessor effectively prevents the moding of the magnetron.
