PURPOSE:To lengthen the power supply period and elevate the power factor by quickening the start time of the power supply period, and delaying the finish time of the power supply. CONSTITUTION:Two sets of transformation type of charging/discharging circuits Q1 and Q2 are connected in forward series. One end of an AC power source V is connected to the middle between the forward series circuits Q1...Q2. The other end of the AC power source V is connected to both ends of the forward series circuits Q1...Q2 through rectifiers D30 and D40, respectively. The direction of each rectifier D30 and D40 is determined to charge each transformation type of charge/discharging circuits Q1 and Q2 in forward direction with the AC power source V. |
