In Half wave Rectifier, we remove the negative Half Cycle of AC wave by using one diode, while in Full Wave Rectifier we convert the negative half cycle of AC into positive cycle using 4 diodes. Also, there will be an increased ripple factor which means that the noise will be high, and extended filtering is needed to provide constant DC output. 1 shows the circuit, of a half-wave voltage doubler. 1-1.

HALF WAVE RECTIFIER CIRCUIT A. The main advantage of a full-wave rectifier over half-wave rectifier is that such as the average output voltage is higher in full-wave rectifier, there is less ripple produced in full-wave rectifier when compared to the half-wave rectifier. Resistor ( RL 1 kilo ohm) C. PROCEDURE. Full-wave rectifier circuits are used for producing an output voltage or output current which is purely DC. B. MATERIAL AND EQUIPMENT. Half Wave Rectifier can be used to obtain the desired level of dc voltage by using Step up or Step down Transformer. Since the output of the half-wave rectifier is still a pulsating DC voltage, the electrolytic capacitor here is used to filter the output of the rectifier and produce a smooth DC voltage. It results a current Id1 through the load R. Full Wave Center Tapped Rectifier As evidenced in Figure 6-5, the V pp of the secondary was 24.5 V with a frequency of 60 Hz.

Half Wave and Full Wave Rectifier In Half Wave Rectifier, when the AC supply is applied at the input, a positive half cycle appears across the load, whereas the negative half cycle is suppressed.This can be done by using the semiconductor PN junction diode. 2 shows the circuit diagram for a half wave rectifier. Diode as a Rectifier:A rectifier is a device that converts alternating current to direct current. This value represents one half of the non-tapped secondary, as one half of the secondary winding was devoted to the top half of the wave while the other half was for the lower half of the function. What do you mean by rectification? 6. It is a simple diode or a group of diodes which converts AC (Alternating Current) voltage into DC (Direct Current). Semiconducting diode performs this work effectively. OBJECTIVES Through this experiment, one can gain enough knowledge to be able to measure, draw and calculate the DC output voltages of half-wave and full-wave rectifier circuits. Half-wave Rectifier: Consider The Half-wave Rectifier Given In Fig. The student can make a rectifier circuit. The circuit is simply the combination of a single diode in series with a resistor, where the resistor is acting as a load. It can be used to obtain the desired level of dc voltage (using step up or step down transformers). The simplest kind of rectifier circuit is the half-wave rectifier.The half-wave rectifier is a circuit that allows only part of an input signal to pass. In full wave rectifier, if we consider a simple sinusoidal a.c voltage, both the negative half cycle or the positive half cycle of the signal is allowed to move past the rectifier circuit with one of the halves flipped to the other halve such that we now have two positive or negatives halves following each other at the output.
