A section of the DC drive that converts the AC power supply into a DC source.

An array of diodes used to convert Alternating Current to Direct Current. Single-phase bridge rectifiers use 4 diodes, 3-phase bridge rectifiers use 6 diodes.

A diode bridge rectifier is a non-controlled full wave rectifier that produces a DC voltage at the output when supplied by alternating voltage at the input. For details on bridge diode, click here.

A circuit using four diodes to provide full wave rectification. Converts an AC voltage to a pulsating DC voltage.

A full-wave rectifier where the diodes are connected in a bridge circuit (two of them are always conducting at any given time). This allows the current to the load during both the positive and negative alternation of the supply voltage. This is the most common type of rectifier circuit to produce a unidirectional voltage for an alternating input.
