Switching Function Converter Controlled by Averaged Firing Pulses

This example shows the advantages of power electronics converters that can be simulated using one of four selectable modeling techniques

Description

The converter in the circuit 0 is modeled by a switching function controlled by firing pulses produced by a PWM generator operating at 25 microseconds. The circuit 1 also uses a switching function converter and a PWM generator but is sampled at 5 microseconds. The converter in the circuit 2 is modeled by a switching function controlled by firing pulses averaged over a period of 25 microseconds. In this case, the PWM generator is in continuous mode.

Simulation

Run the simulation and look at the simulation results to observe that good performance is obtained with the use of averaged pulses at higher sample time period, when compared to the performance obtained with regular pulses at lower sampling time.
