INTRODUCTION Although in our daily life we use A.C. current devices. But rectifier is a ‘Electronic device which converts A.C. power into D.C. power’. The study of the junction diode characteristics reveals that the junction diode offers a low resistance path, when forward biased, and a high resistance path, when reverse biased. This feature of the junction diode enables it to be used as a rectifier. The alternating signals provides opposite kind of
biased voltage at the junction after each halfcycle. If the junction is forward biased in the first halfcycle, its gets reverse biased in the second half. It results in the flow of forward current in one direction only and thus the signal gets rectified. In other words, we can say, when an alternating emf signal is applied across a junction diode, it will conduct only during those alternate half cycles, which biased it in forward direction.

Mainly we have two types of rectifier: 1. Half wave rectifier. 2. Full wave rectifier.
When a single diode is used as a rectifier, the rectification of only one-half of the A.C. wave form takes place. Such a rectification is called half-wave rectification. The circuit diagram for a half-wave rectifier is shown in figure.
: It is based upon the principle that junction diode offers low resistance path when forward biased, and high resistance when reverse biased.
: The A.C. supply is applied across the primary coil(P) of a step-down transformer. The secondary coil(S) of the transformer is connected to the junction diode and a load resistance RL. The output D.C. voltage is obtained across the load resistance(RL)
: Suppose that during the first half of the input cycle, the junction diode gets forward biased the conventional current will flow in the direction of the arrow-heads. The
upper end of RL will be at positive potential w.r.t. the lower end. During the negative half cycle of the input ac voltage, the diode is reverse biased. No current flows in the circuit, and therefore, no voltage is developed across (RL). Since only the positive half cycle of the input appears across the load, the ac input is converted into pulsating direct current (dc).
1. Half Wave Rectification requires only a single rectifier to work. 2. Half Wave Rectification is significantly cheap.
1. Half wave rectification involves a lot of wastage of energy and hence it is not preferred. 2. Some small current flows during reverse bias due to minority charge carriers. As the output across (RL) is negligible.
