What is a Bridge Rectifier?

A Bridge Rectifier is an electrical component used to convert alternating current (AC) to direct current (DC) in a circuit. It is made up of four diodes arranged in a specific configuration. When an AC voltage is applied to the input, the diodes ensure that the current flows in only one direction, effectively converting the negative portion of the AC waveform to positive, resulting in a pulsating DC output.

The four diodes are arranged in a bridge configuration, which allows the circuit to rectify both the positive and negative halves of the AC cycle. This is different from a single-diode rectifier, which only rectifies half of the AC cycle.

The output from a Bridge Rectifier is not a pure DC signal though, as it still contains ripple voltage due to the pulsating nature of the rectified waveform. However, the Bridge Rectifier is a key component in converting AC power from a wall outlet into the DC power needed to operate electronic devices and components such as radios, televisions, and power supplies for various electronic circuits.

In addition to its primary function of converting AC to DC, Bridge Rectifiers are often used in conjunction with smoothing capacitors to reduce the ripple voltage in the output, resulting in a more stable DC signal. This combined circuit is commonly referred to as a “full-wave rectifier.” Easby Electronics can also help with capacitor suggestion/supply to assist design engineers at the design stage.

Easby Electronics offer a wide range of Bridge Rectifiers from long-term partner Taiwan Semiconductor. They are widely used in various electronic applications due to their simple design and effectiveness in converting AC power to DC power, making them an essential component in many power supply circuits and electronic devices.
