The circuit is called a "half wave rectifier" since only one half, in this case the positive half, of the input appears at the output. Half-wave rectifiers are used to convert AC voltage to DC voltage, and only require a single diode to construct. 2. Figure 2 shows the classical full-wave filter, and Figure 3 shows the full-wave bridge rectifier. In order to produce steady DC from a rectified Which is smaller than the corresponding RF value of the half – wave rectifier (see example 3.1 in lecture 3). 4. A half wave rectifier is defined as a type of rectifier that only allows one half-cycle of an AC voltage waveform to pass, blocking the other half-cycle.

In order to produce a constant DC voltage, we need to suppress the ripples of a DC voltage. Experiment No.10 Half wave Single Phase Uncontrolled Rectifier Objective : To study the single phase half wave rectifier behavior for different types of load. For this reason you can not view both input and output simultaneously on an DSO. 2.1 Objective of the experiment . It can be used to obtain the desired level of dc voltage (using step up or step down transformers). Diode Rectifier Circuits Include: This V pp voltage was converted to V RMS in accordance with the formula V RMS = V pk √ 2 ; in this case V RMS = 17.33 V. 1. There are two types of rectifier circuits: (i) Half-wave rectifier and (ii) Full-wave rectifier. Half-wave rectifier circuit with oscilloscope Obtained data Figure 6. During the negative half cycle, the diode is reverse biased and it is equivalent to an open circuit, hence the current through the load resistance is zero. Efficiency, eta is the ratio of the dc output power to ac input power: 1. Half-Wave Rectifier Figure 2-2: Half-wave rectifier 1. In order to build an efficient & smooth DC power supply, a full wave rectifier is always preferred. The channel 2 is represented by the blue color, output voltage across series resistors.
