The Bridge rectifiers are more complex than traditional FWR’s and require four (4) diodes to function, but they can be used with a normal transformer whereas an FWR requires a center tapped transformer and are therefore often cheaper. The following table provides a comparison of each type of rectifier. Type Number of Diodes Transformer Type Output Half-Wave Rectifier 1 Normal Half-wave Full-Wave Rectifier 2 Center Tapped Full-wave Bridge Rectifier 4 Normal Full-wave A full-wave rectifier converts an AC waveform into DC. It consists of a center tapped transformer and two diodes. The output is measured across the load (RL). Full-wave rectifiers build on the structure of half-wave rectifiers, and can be thought of as a modified version of ...

Students will first simulate and build the rectifier to gain an understanding of the purpose of a rectifier. Then, students will use LabVIEW to explore the individual components of the rectifier in order to visualize and understand how these components limit its operating range. Advanced students can explore ways to overcome the threshold voltage limit when using diodes in a rectifier or learn more about programming practices and user-friendliness. Introduction A rectifier is a diode circuit that converts an alternating current (AC) waveform into a waveform that has constant polarity (also sometimes called a direct current or DC waveform), either always negative or always positive depending on the direction of the diodes. There are two major classifications of rectifiers, half-wave and full-wave rectifiers. Half-wave rectifiers are so called because they only pass through one polarity of the circuit while the opposite polarity is removed. Full-wave rectifiers reproduce the whole waveform, but with on...

Full Wave Rectifier Electric circuits that convert AC to DC are known as rectifiers. Rectifiers are classified into two types as Half Wave Rectifiers and Full Wave Rectifiers. Significant power is lost while using a half-wave rectifier and is not feasible for applications that need a smooth and steady supply. For a more smooth and steady supply, we use the full wave rectifiers. In this article, we will be looking into the working and characteristics of a full wave rectifier. Table of Contents: • • • • • • • • • • • • Defining Full Wave Rectifiers A full wave rectifier is defined as a rectifier that converts the complete cycle of alternating current into pulsating DC. Unlike halfwave rectifiers that utilize only the halfwave of the input AC cycle, full wave rectifiers utilize the full cycle. The lower efficiency of the half wave rectifier can be overcome by the full wave rectifier. Full Wave Rectifier Circuit The circuit of the full wave rectifier can be constructed in two ways. The first method uses a centre tapped transformer and two diodes. This arrangement is known as a centre tapped full wave rectifier. The second method uses a standard transformer with four diodes arranged as a bridge. This is known as a bridge rectifier. In the next section, we will restrict the discussion to the centre tapped full wave rectifier only. You can read our article on The circuit of the full wave rectifier consists of a step-down transformer and two diodes that are connected and centre ta...

We can further classify full wave rectifiers into: • Centre-tapped Full Wave Rectifier • Full Wave Bridge Rectifier Centre-tapped Full Wave Rectifier Construction of Centre-tapped Full Wave Rectifier A centre-tapped full-wave rectifier system consists of: • Centre-tapped Transformer • Two Diodes • Resistive Load Centre-tapped Transformer: – It is a normal This type of construction divides the AC voltage into two equal and opposite voltages, namely +Ve voltage (V a) and -Ve voltage (V b). The total output The circuit diagram is as follows. Working of Centre-tapped Full Wave Rectifier We apply an AC voltage to the input This will lead to forwarding bias in diode D 1 and cause 2 is in reverse bias and will block current through it. During the negative half-cycle of the input AC voltage, terminal 2 will become positive relative to terminal 2 and centre-tap. This will lead to forwarding bias in diode D 2 and cause current to flow through it. During this time, diode D 1 is in reverse bias and will block current through it. During the positive cycle, diode D 1 conducts, and during the negative cycle, diode D 2 conducts and during the positive cycle. As a result, both half-cycles are allowed to pass through. The average output DC voltage here is almost twice the DC output Output Waveforms Filter Circuit We get a pulsating DC voltage with many ripples as the output of the centre-tapped full wave rectifier. We cannot use this pulsating for practical applications. So, to convert the ...
