Advances in FPGA Based PWM Generation for Power Electronics Applications: Literature Review

The use of Field Programmable Gate Arrays (FPGAs) for implementing different types of Pulse Width Modulation (PWM) controllers has increased steadily in the last few years. They become dominant tools for implementing different types of PWM due to the flexibility they provide compared to other Digital Signal Processors (DSPs). Different PWMs have been implemented for single and three phase circuits such as Digital PWM (DPWM), Sinusoidal PWM (SPWM), Space Vector (SVPWM), carrier phase shifted SPWM (CPS-SPWM), Third Harmonic Injection Sinusoidal Pulse Width Modulation (THISPWM) using FPGA boards. This paper presents a systematic review for the implemented PWM controllers based on FPGA. It describes in detail their types, architectures, and intended applications they used for. It also addresses the main contributions, advantages, and disadvantages of different research paper in this area. Current limitations and future development have been drawn based on highlighting the implemented and unimplemented PWM based on FPGA.
