  1. The conventional switching power supply usually use a diode rectifier followed by a bulk capacitor to convert ac voltage to dc voltage, resulting in the pulsating waveform of the input ac line current, low power factor ( generally 0. 65 ) and high harmonic line current

    傳統的開關電源設備通常採用二極體橋來進行整流和一個較大的電解電容來進行濾波以實現輸入電壓的交直流轉換，導致輸入電流為一個很窄的脈沖波並含有較多的諧波分量，功率因數變低（通常只有0 . 65 ） 。
  2.

  5. Single phase ac reactive power meter : light column display single screen digital display, outline dimension 80160 mm, rs - 485 standard serial communication ; transmission output ma ; high low limit alarm function switch power supply input voltage 380 v input current 05 a display range 01900 var

    單相交流無功功率表光柱顯示單屏數字顯示外形尺寸80160 rs - 485標準串列通訊變送輸出4 20 ma ，上下限報警功能開關電源供電;輸入電壓380v ;輸入電流05a ;顯示量程0 1900var 。
  6. The other way is to use a single - stage power processor to correct power factor and regulate voltage simultaneously. however, the technology has only been applied in low power of single - phase ac input and has no use in high power of three - phase. so, the three - phase high power supply as the main emi equipment is becoming one of the hot points in international research

    目前，這僅在輸入電源為單相的變換器中實現，而且不是軟開關，仍存在emi ；對于污染問題更嚴重的輸入電源為三相三線的較大功率的變換器，則未見報道，同時，三相大功率的電磁污染治理問題也成為國際研究的熱點之一。
  7. Abstract : the multifunctional inverter power sourcethe handy inverter welding, plating & charging manchine, developed with advanced inverter and micro - electronics control techniques, adopts “ half - bridge power expansion supply midpoint voltage autocontrol setting ”, and technically and effectively having solved inverter subvision of inverter power expansion circuit for leaning magnetism, reliability of high - power inverter setting, achives combination of constantcurrent and constantvoltage export, and realizes low - voltage dc and high - voltage ac double power supply
