CONSTRUCTION:

A 3-phase 415V AC supply is fed into an IGBT-based rectifier circuit. This circuit employs Insulated Gate Bipolar Transistors (IGBTs) for controlled switching, enabling precise pulse-width modulation (PWM). The output is regulated from 0 to 415V AC and is then connected to a step-down transformer. The secondary side of the transformer features a diode rectifier, ensuring efficient conversion of the AC output to a stable DC voltage.
