# DESIGN AND IMPLEMENTATION OF AN FPGA-BASED SVPWM IC FOR PWM INVERTERS

### Cheng-Hung Tsai, Hung-Ching Lu

#### Abstract

This paper presents a new circuit design scheme of the space-vector pulse-width modulation (SVPWM) strategy, including linear and overmodulation ranges. The proposed scheme has been developed using the state-of-the-art field-programmable gate array (FPGA) technology. The SVPWM control integrated circuit (IC) can be realized by using only a single FPGA (Cyclone) from Altera, Inc. Experimental results show that this controller can present an excellent drive performance and its switching frequency, which can be set to over 100kHz, is adjustable as well as its deadtime. The output fundamental frequency can be adjusted over 2000Hz. This SVPWM IC can be included in the digital current control loop for stator current regulation. The IC also provide a simple hardware and low cost for high-performance ac drives.
