摘要： An electrically isolated temperature sensor for use with a printer, copier, or all-in-one fuser. The fuser includes an AC driven heater to which a thermistor is mounted for sensing the temperature of the fuser heater. A resistance of the thermistor controls the period of a periodic signal generated by an astable multivibrator. An optical isolator isolates the printer fuser from down line processing circuits, and transfers the periodic signal to such processing circuits. The printer fuser employs a separate floating ground that is not connected to other DC circuits of the printer. With this arrangement, any AC power that is inadvertently coupled from the heater to the DC circuits of the fuser is isolated thereto. The AC power is isolated to the fuser and cannot be propagated through the fuser to other down line circuits of the printer.

摘要： An improved laser printer is provided that keeps its fuser at a standby temperature that is somewhat raised above the ambient temperature, which allows the printer to operate more quickly (to begin printing the first page) when a print job arrives at the printer. The time needed to raise the fuser's temperature is minimized, so that other printer operations become the determining factor in the time to first print parameter. The electrical energy that energizes the fuser is provided in a form that prevents light flicker, by use of AC waveform phase control, or by use of integer half cycle control. The present invention uses closed-loop feedback control, and the type of controller is a PID controller.

摘要： An improved control method is provided that combines conventional ON-OFF control and conventional phase-angle control to reduce the AC inrush current to an electrical load, such as a tungsten halogen lamp used as a heating element in a laser printer, so that the power control circuit can satisfy both the European flicker and European harmonic requirements. Phase-angle control is applied to the load for a very short time period when it is initially energized, then the control circuit quickly switches from phase-angle control to standard ON-OFF control to reduce the harmonics generated by conventional phase-angle control methodologies. The electrical load exhibits three possible states: power full OFF, power ramp-up, and power full ON. During the power ramp-up state, power supplied to the load is adjusted by delaying the phase angle of the firing pulse relative to the start of each AC half cycle. Depending upon whether or not the system demand has been satisfied, the load's state can be changed from either power ramp-up to power full ON, or from power ramp-up to power full OFF. The phase-angle control methodology used during the power ramp-up state must be of sufficient time duration to reduce the amount of flicker to pass the European flicker test. However, this power ramp-up time interval must also be as short as possible to keep the harmonics as small as possible to the load, without the requirement of adding a large AC current harmonic attenuation inductor, which would otherwise be needed to pass the European harmonic test.
摘要翻译：提供了一种改进的控制方法，其结合常规的ON-OFF控制和常规的相位角控制，以减少对诸如在激光打印机中用作加热元件的卤素灯等电负载的AC浪涌电流，使得功率控制电路可以满足欧洲闪烁和欧洲谐波要求。当初始通电时，相位角控制在很短时间内被施加到负载上，然后控制电路从相位角控制快速切换到标准的ON-OFF控制，以减少常规相位角控制方法产生的谐波。电气负载表现为三种可能的状态：电源全关，功率提升和电源全开。在功率提升状态期间，通过相对于每个AC半周期的开始延迟点火脉冲的相位角来调节提供给负载的功率。根据系统需求是否得到满足，负载的状态可以从功率提升到电力全部接通，或者从功率提升到全部关断。在功率提升状态期间使用的相位角控制方法必须具有足够的持续时间，以减少闪烁量以通过欧洲闪烁测试。然而，这种功率提升时间间隔也必须尽可能短，以保持谐波尽可能小到负载，而不需要增加大的交流电流谐波衰减电感器，否则将需要通过欧洲谐波测试。

摘要： A circuit includes a switching device for controlling a power signal to be applied to a heating device. A control circuit is configured for comparing a temperature signal, indicative of the temperature of the heating device, to a temperature setpoint to generate a gate pulse signal that controls the duration of the power signal to be applied to the heating device. The control circuit is further configured for comparing the duration of the power signal to be applied to the heating device to a minimum pulse duration and, if the duration of the power signal to be applied to the heating device is at least equal to the minimum pulse duration, providing the gate pulse signal to the switching device.
