摘要： This invention is intended to control the amount of power to be supplied to a fusing heater below a maximum applicable current value. The engine controller supplies electricity to both of two heating bodies at the same fixed duty D1. At a phase angle α1 corresponding to the fixed duty D1, pulse signals ON1 and ON2 are issued in response to a ZEROX signal as a trigger. A current value I1 is detected based on a HCRRT signal from the current detection circuit. The engine controller calculates an upper limit of applicable power duty Dlimit based on the detected current value I1, the fixed duty D1 and the preset applicable current value Ilimit. Then, a PI temperature control is performed at a duty below the upper limit duty Dlimit.

摘要： An image heating apparatus includes first and second heat generating elements, first and second driving elements provided in a passage from a commercial power source to the heat generating elements, respectively, and a portion controlling the driving elements at a control level depending on a detection temperature. At the control level, a renewing period is two cycles of a waveform of an alternating current of the power source or an integral multiple thereof. The control portion controls, during a period when the control portion controls the driving elements at one control level, the driving elements so that the heat generating element to which the power is to be preferentially supplied is switched from the first to the second driving element and the waveform of the alternating current passing through each of the heat generating elements keeps symmetry of positive and negative half-cycle components with respect to a zero-voltage line.

摘要： A period of a first edge, a voltage change in a first direction of a first pulse signal fed from a zero-crossing detecting circuit, is detected. A second edge, a voltage change in a second direction opposite to the first direction, is generated when a time period equal to half the period of the first edge has elapsed from the next first edge. In response to a second pulse signal generated from the first and second edges, phase control of power to be supplied to heating elements is performed by using triacs. In this manner, during power control using a signal from the zero-crossing detecting circuit as a trigger signal, is achieved stable power control which enables tracking even though the power supply frequency fluctuates, and which is impervious to the effect of the positive or negative polarity of an input power supply.
