A full wave doubler circuit diagram is shown in the following figure. Like the half-wave doubler, it also consists of two diodes and two capacitors, but the circuit''s configuration differs. During the positive half cycle of input ac voltage, the diode D 1 conducts and charges the capacitor C 1 to the maximum voltage V m.
However, during the synchronous mode of operation, the diode is substituted by the switch, either IGBT or MOSFET, thereby reducing the losses, and hence the efficiency of the converter gets enhanced.
