Retificador de onda completa

In this circuit the input is provided to the center-tapped transformer as it reaches the secondary winding the voltage is divided into two halves. During the positive half of the input cycles, the diode D1 is in forwarding bias condition indicating the conducting mode and the diode D2 is in the non-conducting mode because it is in reverse bias condition. The flow of current is observed at the terminal of diode D1. During the negative half of the cycle, the diode D2 conducts because of the center-tapped transformer property and the diode D1 is in reverse bias condition that is in non-conduction mode. During this consequence the terminal at D2 one can find the flow of current through it and at D1 there is no evident flow of current or the current is blocked at D1 terminal. Due to this , during positive cycle diode D1 is in the range of conduction and when the negative cycle is provided the diode D2 will be in the conducting stage. Hence both the cycles are utilized here for rectification without any loss of input power. Hence we can say that the average output voltage of the half-wave rectifier is doubled compared to that of the half-wave rectifier.
