Abstract :
Pulsewidth modulation, similar to voltage-space vector control in switches utilizing a field programmable gate array, is compared with PSpice simulation in a three switches converter is presented. The PSpice simulation is used in time domain simulation of the rectifier and inverter circuit. The PSpice PWM simulation modelled is compared with the experiment which is implemented in a field programmable gate array based on a carrier frequency of 19.2 kHz. The PWM is applied to the converter operated as a step-down converter where the output voltage can be controlled by the modulation index in the range of 0 to 1.5 Vˆ ph. Simulation and experimental results are provided to demonstrate the effectiveness of the proposed model
