Description

Block Rectifier (Three-Phase) Simulates a three-beam diode bridge circuit that converts a three-phase AC voltage to a DC voltage. The figure shows an equivalent circuit of a three-beam diode bridge. rectifier three phase

In the parameters group Charge Dynamics You can select the type of diode to be used in the three-shoulder bridge circuit. The table shows how to configure the parameter Model dynamics depending on your goals.
