FPGA Applications in DC-AC Converts: A Single Chip Implementation of Spwm and SVPWM Modulators

In the past decade, the development in the field of FPGA has found a lot of applications in electrical power conversion applications. The SPWM and SVPWM are the most commonly used PWM schemes in the three phase inverters due to their advantages. This paper presents single chip implementation of two commonly used PWM schemes such as SPWM and SVPWM in a single FPGA using Q-format data representation. It also provides the guidelines and quick references for practicing engineers and researchers in the field of FPGA based development to select the suitable digital controller based on the switching frequency, speed of the algorithm and single chip applications.
