1. a circuit (100,200), it comprises:

  • Be connected in series to first switch (120,220) of first discharge resistor (130,230), described first switch (120,220) and described first discharge resistor (130,230) are connected to positive direct-current (DC) bus (170,270);

    Be connected in series to the second switch (122,222) of second discharge resistor (132,232), described second switch (122,222) and described second discharge resistor (132,232) are connected to negative DC bus (180,280);

    AndBe used to store the capacitor group (140) of positive dc voltage and negative dc voltage, described capacitor group (140) comprises and described first switch (122,222) and described first discharge resistor (130,230) Bing Lian first capacitor (142), with with described second switch (122,222) and second discharge resistor (132,232), second capacitor (144) in parallelWherein said first switch (120,220) be independent of described second switch (122,222) operation is to pass through described first discharge resistor (130 with positive dc voltage,

         230) discharge and described second switch (122,222) be independent of described first switch (120,220) operation will be will bear dc voltage by described second discharge resistor (132,232) discharge.
