single phase half wave rectifier in which when the input is applied AC and the output is DC . When we applied the ac voltage , positive peak will appear on the diode and diode will only conduct when anode is greater than cathode side . in this anode is greater than cathode so cathode will conduct and voltage appear on the output side and output in the dc appear on the resister .
when the negative peak is applied at the diode ,anode side is less than the cathode side so the ideal diode will not conduct and diode will open .so all the voltages appear on the diode and diode act as a short circuit and in the output side voltage will not appear . so in the figure clearly we can see all the waveform and output of the supply .
so thats a single phase rectifier . we get the dc at the output side but the disadvantage is that we cannot get the input voltage at the aoutput side . losses are more in single phase rectfier .
