Half Wave Rectifier
A half-wave rectifier is an electronic circuit, and a type of rectifier that rectifies only half cycle of the waveform. It gets its name from the fact that only half the sine wave of the alternating current passes through it and is converted to direct current. The half rectifier consist a step down transformer, a diode connected to the transformer and a load resistance connected to the cathode end of the diode. The main supply voltage is given to the transformer which will increase or decrease the voltage and give to the diode. In most of the cases, the step-down transformer is used to decrease the supply voltage. This decreased alternating current voltage is given to the diode which is connected serial to the secondary winding of the transformer, diode is electronic component which will allow only the forward bias current and will not allow the reverse bias current.
