Product Specifications

Technical details and manufacturing context for Bridge Rectifier

Definition
A bridge rectifier is a critical component within the Input Filter and Rectifier subsystem that transforms AC input voltage into DC output voltage. It consists of four diodes arranged in a bridge configuration, enabling full-wave rectification where both halves of the AC waveform are utilized, resulting in higher efficiency and smoother DC output compared to half-wave rectifiers.
Working Principle
The bridge rectifier operates by directing current flow through its four diodes. During the positive half-cycle of AC input, two diodes conduct to allow current to flow in one direction through the load. During the negative half-cycle, the other two diodes conduct, maintaining the same direction of current flow through the load. This process converts bidirectional AC into unidirectional DC.
