Hard chrome plating rectifier is a device that converts AC power into DC power, which is mainly composed of two parts: rectifier and filter.

Rectifier is the key component for converting AC power into DC power. In hard chrome plating rectifier, a rectifier bridge circuit is generally used for rectification operation. The rectifier bridge circuit consists of four diodes. Through different working modes, it can convert the positive and negative half-cycles of AC power into forward current, thereby realizing unidirectional transmission of current.

The filter is a device used to smooth the rectified DC signal. In hard chrome plating rectifier, capacitors are usually used as filters to eliminate fluctuations and ripples in DC signals and stabilize the output voltage.

The working principle of the rectifier is to convert the input AC power into DC power through a rectifier bridge circuit, and then smooth the DC signal through a filter to finally obtain a stable DC output. This can be used to provide a stable power supply for hard chrome plating equipment.
