DCSimulation and analysis of AC DC converter circuit by using alternative transient program

Abstract EN

In this article, an efficient method for converting AC voltage to DC voltage using full-wave bridge rectifier has been presented.

The rectifier output of, however, includes unwanted ripples.

In most cases the ripple must be below the specific limit.

In this article an attempt is made to reduce the ripple by means of a filter circuit that consists of a capacitor or an inductance or both in order to restrict the ripple.

A mathematical formula for computing the value of a single capacitor or filter inductance is provided when the capacitor or inductance is being used separately, but if the capacitor or inductance are being used together, there is no mathematical formula for calculating their values to control ripple count.

In the paper, the Alternative Transient Program (ATP) has been used to simulate the switching of the circuit to validate the circuit's operation in all three conditions.

The difference between the two results indicates that the computed and stimulated results are nearly identical.

The results analysis shows that the Combined Capacitor Inductance Filter Design Method is the most suiTable method for controlling the ripples at a certain level.
