ESH3DHE3/9AT

The ESH3DHE3/9AT, also known as a full-wave bridge rectifier, is a diode device that converts alternating current (AC) to direct current (DC). It is composed of four elements, and when it\'s used within a power supply, can help simplify design and reduce system cost. This article explains the application fields and working principles of the ESH3DHE3/9AT.

Application fields of ESH3DHE3/9AT

The ESH3DHE3/9AT is commonly used in the following applications:

• Power supplies and computer fans
• DC motors and drives
• Mobile phone chargers
• Home appliances

These applications all require a reliable and robust DC power source, and an ESH3DHE3/9AT helps to provide this. It also helps to protect components from voltage spikes and power surges.

Working principle of ESH3DHE3/9AT

The ESH3DHE3/9AT is made of four diodes, arranged into a pattern known as a ‘full wave bridge rectifier’ configuration. The four diodes in the rectifier are connected in such a way that when an AC voltage is applied to the terminals, they form a closed ‘bridge’ circuit which converts the AC into DC.

During the positive half cycle of the voltage waveform, diodes D1 and D3 turn on and allow current to flow from the top terminal to the bottom terminal. During this time, diodes D2 and D4 are reverse biased and do not conduct. During the negative half cycle of the voltage waveform, diodes D2 and D4 turn on and allow current to flow from the bottom terminal to the top terminal. During this time, diodes D1 and D3 are reverse biased and do not conduct. The result is a continuous flow of DC from one terminal to the other.

Another advantage of this rectifier configuration is that it produces an output voltage which is almost equal to the input voltage, less the forward voltage drops of the four diodes. This makes the ESH3DHE3/9AT an ideal choice for power supplies and DC motors.

In summary, the ESH3DHE3/9AT is a full-wave bridge rectifier, composed of four diodes, which converts AC to DC. It is commonly used in power supplies and other DC motor applications, and helps to protect components against voltage spikes and power surges.
