Simulation and Experimental Validation of AC to AC Converter Waveform and Power Consumption using the Integral Cycle PWM Technique

Huang Shen C, Wadah EEB, Albert FYC

In this paper, integral cycle PWM AC to AC converter waveform and power consumption were successfully simulated and validated by experiment. The simulated waveforms are considerably similar to the experimental waveform. Two types of gate drive were used, which are BJT transistor and Optocoupler. When BJT was used, the experimental waveform was considerably different from the simulated waveform. This problem was overcome by using Optocoupler. 100 Hz switching frequency has the highest power and less error (difference between the simulated and the experimental) among the other switching frequency. The integral cycle PWM generated by using Tiva C Launchpad and Code Composer Studio (CCS) software were used to write program. This topology has the lowest THD and the high power factor among the other topologies.
