    摘要： An induction heating cooker comprises an inverter circuit. The inverter circuit has a heating coil and a resonance capacitor that resonates with the heating coil to generate high-frequency electric power with which an object to be heated is inductively heated. The cooker further includes a phase comparator for comparing the phase of a first signal that correlates to the phase of an output voltage of the inverter circuit with the phase of a second signal that correlates with the phase of a current flowing to the resonance capacitor; a phase difference setter for setting the phase difference of the first and second signals; and a frequency controller for controlling an oscillation frequency of the inverter circuit according to a signal from the phase difference comparator to establish the phase difference set by the phase difference setter.

    摘要： An object to be heated, such as a cooking utensil or vessel, is placed on a top plate. An inventer has a resonating circuit comprising an induction heating coil arranged below the top plate and a resonating capacitor connected to the coil, and a circuit for supplying high-frequency power to the resonating circuit in order to generate a high-frequency magnetic field from the induction heating coil and to induce an eddy current in the object to be heated. An inverter power level control data generating unit outputs inverter power level control data according to the relationship between the high-frequency power from the inverter circuit and a repulsion force acting on the object to be heated, based on the high-frequency power. The inverter power level control data is data for controlling the level of the high-frequency power from the inverter circuit so as to prevent the object to be heated from floating over a placing surface of the top plate, due to the repulsion force. A control unit feeds back the inverter power level control data from the control data generating unit to the inverter circuit.

    摘要： A heating apparatus such as a microwave oven includes a magnetron supplying microwaves into a heating chamber so that food accommodated in it is heated and a microcomputer-based control circuit. The control circuit discriminates the food among three conditions, that is, a first condition in which the food is not wrapped in a wrap film, a second condition in which the food is wrapped in a wrap film, and a third condition belonging neither to the first nor to the second condition. Based on the results of discrimination, the control circuit calculates a remaining heating time.

    摘要： In an inverter type high frequency heating apparatus such as an electromagnetic cooker and a microwave oven, an insulated gate bipolar transistor is employed as a switching element. A parallel circuit arranged by a capacitor and a resistor is interposed between a gate electrode of the gate insulated bipolar transistor and a gate driver circuit so as to prevent a power loss, or ringing effect when the gate insulated bipolar transistor is turned off.

    摘要： In an electromagnetic cooking apparatus, low heating power control is carried out by turning ON/OFF a DC power supply circuit, or rectifier circuit, at a commercial frequency lower than an inverting frequency of DC/AC inverter. The electromagnetic cooking apparatus includes: a DC (direct current) power supply for producing DC power from low-frequency AC (alternating current) power; a DC-to-AC inverting circuit coupled to the DC power supply and including a switching element and also a heating coil, for inverting the DC power inputted from the DC power supply into high-frequency AC power so as to heat a metal pan by energizing the heating coil with the high-frequency AC power, thereby electromagnetically inducing eddy currents within the metal pan; a monitoring circuit for monitoring switching conditions of the switching element so as to output a switching condition signal; and an ON/OFF-controlling circuit for turning ON/OFF power supply operation of the DC power supply, or inverting operation of the DC/AC inverter circuit in response to the switching condition signal at a timing period defined by a time constant smaller than a thermal time constant determined by a heat capacity of a metal material of the pan.
