摘要： A first X capacitor is connected between one of a plurality of hot line sections of a hot line that is located at an output side of a first relay as viewed from a commercial alternating-current power supply, and one of a plurality of neutral line sections of a neutral line that is located at an input side of a second relay as viewed from the commercial alternating-current power supply. A second X capacitor is connected between one of the hot line sections that is located at the output side of the first relay as viewed from the commercial alternating-current power supply, and one of the neutral line sections that is located at an output side of the second relay as viewed from the commercial alternating-current power supply.

摘要： When an image forming apparatus shifts to a power saving mode, a controller unit further reduces power consumption by switching AC current on/off every predetermined amount of time. When AC current input from a commercial AC power supply is turned off, a DC voltage generating circuit normally can no longer supply a DC voltage, rendering the controller unit unable to operate. Accordingly, the controller unit operates using a charge accumulated in a smoothing capacitor while the AC current is not being supplied. An AC cutting circuit is switched on before a both-end voltage at the smoothing capacitor drops below a lower limit of operation voltage of the DC voltage generating circuit, and the smoothing capacitor is recharged.
摘要翻译：当图像形成装置转换到省电模式时，控制器单元进一步通过每隔预定时间量切换交流电流来开启/关闭功率消耗。当从商用交流电源输入的交流电流关闭时，直流电压发生电路通常不能再提供直流电压，使得控制器单元无法运行。因此，控制器单元在没有提供AC电流的同时使用积累在平滑电容器中的电荷进行操作。在平滑电容器的两端电压下降到低于直流电压产生电路的工作电压的下限之前，交流切换电路被接通，平滑电容器被再充电。

摘要： When a detection signal indicates that a switch has switched off, a first relay cuts off the supply of alternating current from a commercial alternating-current source to a third DC power source and terminates a first load such as a motor and a high-voltage power source. When the detection signal indicates that the switch has switched off, a control circuit executes shutdown processing for safely terminating an operation of a second load such as a hard disk drive. When the shutdown processing is complete, the control circuit outputs a signal for terminating an operation of a second DC power source. When the shutdown signal is input, a second relay terminates the operation of the second load by cutting off the supply of the alternating current from the commercial alternating-current source to a second DC power source.
