Abstract

The design of hardware and software generation of the synchronous pulse-width modulation (PWM) suitable for the three-phase bi-directional AC-DC power converter is presented. The switching of the power devices is modulated by synchronous PWM implemented in an XC-3042 field programmable gate array (FPGA). There are no mains capture and synchronization problems. The utilization of the switches is based on the voltage-space vector control of an inverter. Displacement factor control is achieved in the design by decrement and increment of the phase-shift counter to give leading or lagging phase angle respectively. Results are provided to demonstrate the effectiveness of the design.
