01 / CONNECTIONS

Follow the terminal markings.

Connect the AC source to the two ~ terminals. Take the rectified output from + and −. Identify these markings on the actual device; the functional diagram does not specify the physical terminal positions.

The bridge output is pulsating DC. Smoothing, regulation, protection and cooling depend on the complete circuit design.

02 / WORKING PRINCIPLE

Two half-cycles.
One output polarity.

In one half-cycle, D1 and D4 conduct. In the other, D2 and D3 conduct. Both paths drive current through the load in the same direction. The animation shows conventional current; its timing is illustrative.

The bridge output is pulsating DC; the bridge alone does not smooth or regulate it.
