<P>PROBLEM TO BE SOLVED: To provide an electricity conditioning device, and a power supply control system and method therefor. <P>SOLUTION: In a power supply control system including a detector 201, a power conditioning device 202 and a resistance type loading device 202, the detector 201 can receive a feedback signal transmitted from the resistance type loading device 202. The detector 201 outputs a control signal of either voltage or current signal. After the power conditioning device 202 receives the control signal, a drive voltage is output by a proportional method. The proportional method is used to output the full-power drive voltage at intervals of continuous output time and to stop outputting the full-power drive voltage at intervals of discontinuous output time. After the resistance type loading device 203 receives the drive voltage, the feedback signal is output to the detector 201. Formation of power harmonics can be reduced efficiently through the operation of using the proportional method to output the full-power drive voltage at intervals of continuous output time and to stop outputting the full-power drive voltage at intervals of discontinuous output time. <P>COPYRIGHT: (C)2012,JPO&INPIT |
