Full wave rectifier diode used at least 2. Working principle is like a half wave rectifier transformer has a center tap, but, like a half wave circuit 2 circuits. That is to say, when half wave positive means the legs on positive.But it is a positive compared to the lower legs The bottom leg is negative when compared to the top and center pin tab. Current flows through the diode D1 back at the center tap. Just half of pressure. On the other hand, in the form of negative wave means the top leg is negative.Current flow through the diode D2 half
.A full wave rectifier bridge
.A diode bridge rectifier used 4. And transformer without center tap working principle is when the legs on a positive lower leg is negative, current flow through the diode 2 outside. When negative wave pin is negative, the lower legs are positive current flow diode 2 medium.Don't break the two parts like full wave normal
.The average value of the output and root-mean-square voltage of full wave rectifier no-load theoretically:
