Full-wave rectifier circuits are used for producing an output voltage or output current which is purely DC. Manufacturing of the center-tapped transformer is quite expensive and so Full wave rectifier with center-tapped transformer is costly. Fig. A Rectifier converts AC into DC. Measure the input voltage V 1 and the output voltage V 2 using both the voltmeter and the oscilloscope. 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. In order to produce steady DC from a rectified AC supply, a filter circuit is required. 8.2.3 Half-wave Rectifier with a Capacitor Filter The half-wave rectifier discussed in Section 2.1 above delivers a pulsating, The half wave rectifier is often used for signal and peak detection. The output voltage and current of this rectifier are strongly influenced by the type of the load. 1. Such a rectification is called half-wave rectification. It can be used to obtain the desired level of dc voltage (using step up or step down transformers). Full wave rectifier In a half wave rectifier, DC is available at its output terminals during one half cycle of the AC input, whereas in a full wave rectifier DC is obtained during both half cycles of the AC input. And, a diode works and allows current in only one direction and blocks it in another one. For half wave rectifier circuits, be sure to use an op amp with a high slew rate. Also, the performance of a half-wave rectifier will be studied and measured. As a result a full wave system is normally used for power rectification. A full-wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. Half-Wave Rectifier Figure 1 shows a schematic diagram of a transformer coupled half-wave rectifier circuit. In a positive half cycle of In a half-wave rectifier, one half of the source waveform is not utilized (power losses) 2. Diodes with high PIV rating are to be used. 2: Structure of the single-phase, single-way, half-wave rectifier Figure 3 shows the waveforms of the voltage at the s econdary and of the current in the load. 2.
