In both cases, rectification is performed by utilizing the characteristic that current flows only in the positive direction in a diode. Full-wave rectification rectifies the negative component of the input voltage to a positive voltage, then converts it into DC pulse current utilizing a diode bridge configuration. In contrast, half-wave rectification removes just the negative voltage component using a single diode before converting to DC. From this, it can be said that full-wave rectification is a more efficient method than half-wave rectification since the entire waveform is used. Also, a ripple voltage that appears after smoothing will vary depending on the capacitance of this capacitor and the load. Given the same capacitance and load, ripple voltage is smaller with full-wave rectification than haif-wave rectification.
It utilizes only half of AC cycle for the conversion process. The Half-Wave Rectifier is unidirectional; it means it will allow the conduction in one direction only. This is the reason that it is called Half Wave Rectifier. While Full-wave Rectifier, is bi-directional, it conducts for positive half as well as negative half of the cycle. Thus, it is termed as full wave rectifier.

To understand the effect of a reservoir capacitor upon the rectified waveform and its mean value. Half wave rectifier has around 0. Design the circuit diagram. Answer the questions listed in the Thoughtful Questions section in the lab manual. This paper. The bridge is composed of four diodes in a diamond shape. January ; DOI:
A Full wave rectifier is a circuit arrangement which makes use of both half cycles of input alternating current AC and converts them to direct current DC. In our tutorial on Half wave rectifiers , we have seen that a half wave rectifier makes use of only one-half cycle of the input alternating current. This process of converting both half cycles of the input supply alternating current to direct current DC is termed full wave rectification. Full wave rectifier can be constructed in 2 ways. The first method makes use of a centre tapped transformer and 2 diodes.
The circuit diagram of half wave rectifier without capacitor is shown in the following figure. During positive half cycle of the input voltage anode of the diode is.
Now we come to the most popular application of the diode : rectification. Simply defined, rectification is the conversion of alternating current AC to direct current DC. This involves a device that only allows one-way flow of electric charge.
The process of converting the AC current into DC current is referred to as rectification. Rectification can be achieved by using a single diode or group of diodes. These diodes which convert the AC current into DC current are referred to as rectifiers.
For the positive half-cycle of the source in this circuit, the diode is on Thus the diode conducts only for one half cycle and results in half wave rectification. The diode is a basic electronic switch that allows current in one direction only.
A half-wave rectifier is a simple circuit that is basically used for converting an AC voltage to the DC voltage. It is used in the end number of electronic devices. Applications of Half wave rectifier. Any rectifier is used to construct DC power supplies. The practical application of any rectifier be it half wave or full wave is to be used as a component in building DC power supplies.
