Rectifier circuits comparison 13 Half-wave rectifier 1. The Half wave rectifier is a circuit, which converts an ac voltage to dc voltage. Apparatus Used : 1. Full-wave Rectifier with Capacitor Filter. Experiment 1 15 Study of cosine firing scheme for single-phase converter Experiment 2 18 Study of half wave controlled rectifier with resistive load. Simple, easy to construct and require a single diode 2. Half wave rectifier using diode: Assemble the half wave rectifier circuit using P-N junction diode as shown in image(1). Connect the circuit as shown in Fig.1, adjust the power supply at 10 V. 2. This article describes the half wave rectifier circuit working. The question logically arises as to which configuration is the best choice for a given application. Fig. Additionally they have high contents of harmonics, which are difficult to filter out and to smooth out the ripple in the rectified AC power. During the positive half cycle, when the secondary winding of the upper end is positive with respect to the lower end, the diode is under forwarding bias condition and it conducts current. 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. So we use step-down transformer in half wave rectifier. Manufacturing of the center-tapped transformer is quite expensive and so Full wave rectifier with center-tapped transformer is costly. A Rectifier converts AC into DC. Fig. 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. It can be used to obtain the desired level of dc voltage (using step up or step down transformers). Half wave rectifier. So, the basic principle on which rectifier works and is constructed is the working of a diode only. High DC output voltage 2. Experiment No.7 Three-Phase half wave Uncontrolled Rectifier Experiment aim The aim of this experiment is to design and analysis of a three phase uncontrolled rectifier. Power … Half-wave rectifier with an RC filter 5- Carrying out the experiment 5-1- Representing the output voltage v O (t) for an Ohmic load resistance - Assemble the circuit as shown in Figure 1 and apply an AC voltage of V S = 6V to terminals 1 and 2. 2. Half-wave rectifier circuit Figure 2. A half wave rectifier clips the negative half cycles and allows only the positive half cycles to flow through the load. Thus it utilizes only the one-half cycle of the input signal. Let us now consider an AC voltage with lower amplitude of 15Vrms and rectify it into dc voltage using a single diode. Experiment 3 21 Study of full wave controlled rectifier (mid- point configuration) with resistive load. Date of Submission : --/--/2014. Disadvantages of Full wave Rectifier: Output voltage is half of the full secondary voltage. And, a diode works and allows current in only one direction and blocks it in another one. experiment. BACKGROUND THEORY AND ANALYSIS Half-wave and full-wave rectification systems procedure a DC level from a sinusoidal input signal with a zero average (DC) level. EXPERIMENT Half-Wave and Full-Wave Rectification OBJECTIVE To calculate, draw, and measure the DC output voltages of half-wave and full-wave rectifier circuits. Experiment Name : Signature _____ _____ _____ Date of Experiment : --/--/2014. In this experiment, we will study three different types of rectifiers with capacitor filter. Half-wave rectifiers can be used, but they are highly inefficient in converting AC power to DC power. is improved. Figure 1: The Half-Wave Rectifier with Capacitive Filtering.
