You always wondered how to build a bridge rectifier, isn’t it? Its very easy, and may be done through the following three simple steps as shown in the diagrams: Take 4 rectifier diodes for example the 1N4007 rectiifer diodes, Pick two diodes, make a cross of their two ends marked wit...

Four diodes can be used to create a full wave bridge rectifier which does not need a power transformer center tap. A bridge rectifier is very efficient and extracts almost twice the voltage from an AC supply as a conventional rectifier. 4 Diode Bridge Rectifier Current Flow During Positive Half...
Electricity is flow of electrons (Negative Charge) from one body to another. In order to understand this is some detail, it is important to understand thestructure of an atom. An atom consists of three elements –electrons, protons and neutrons. Electrons are negatively charged (–) particles,...
This article will examine different faults of a diode bridge rectifier to provide some insight into troubleshooting an AC/DC power supply.
The threat lies in the fact that the reverse voltage inflicted by the inductor tries to make its way through the associated power device such as a BJT with a reverse polarity causing a instant damage to the device. A simple idea to counter this issue is to add a rectifier diode directly ...

A bridge rectifier is used for rectifying the residual AC from the sensing coil, using 1N4148 diodes, so that the resulting DC can be used for further amplification using an op amp circuit. A 741 op amp is set up like a differential amplifier. It is configured to detect the voltage develo...
For our case, we will use a transformer to step down the voltage, followed by a bridge rectifier to convert the AC voltage to DC. Step 3: Connect the Transformer Connect the primary winding of the transformer to the AC power source and the secondary winding to the rectifier. Make sure ...
Figure 3 shows a differential implementation of the output transistors and LC filter in a Class D amplifier. This H-bridge has two half-bridge switching circuits that supply pulses of opposite polarity to the filter, which comprises two inductors, two capacitors, and the speaker. Each half-...
