Design of a universal space vector PWM controller based on FPGA

Abstract

This paper presents a new design scheme of space vector PWM integrated circuit, including linear and overmodulation ranges. The proposed scheme is implemented and verified on a single Xilinx FPGA. Experimental results show that this controller can present an excellent drive performance and its switching frequency, which can be set to 40 kHz, is adjustable as well as its dead time. The SVPWM IC has been used in closed vector control of AC servo drive system.
