Three phase full wave bridge rectifier

Datsen Davies Tharakan

Introduction:
This example shows three phase full wave bridge rectifier circuit. The diode bridge used here implements physics-behavioral diodes representing the semiconductor elements. A three phase full wave bridge rectifier consists of six diodes. For many three phase AC applications, where the full wave bridge serves to convert an AC input into a DC output, the addition of a capacitor may be desired because the bridge alone supplies an output of fixed polarity but continuously varying or "pulsating" magnitude, an attribute commonly referred to as "ripple". For this reason the bridge model includes a filter capacitance. The user may specify the capacitance value, as well as an ESR value, which is optional.
