Implementation of Simple Boost Control Pulse Width Modulation for a Two-Level Three-Phase Quasi-Impedance Source Converter

Abstract

This work presents an implementation methodology of a Pulse Width Modulation (PWM) technique called Simple Boost Control (SBC) for a quasi-Z-Source Converter (qZSC). This converter topology enables boost operations and bidirectional power flow, through the inclusion of an additional switching stage on the conventional three-phase inverter bridge. In this additional stage, referred to as the shoot-through stage, all switches are turned on simultaneously. The implementation is carried out on a Texas Instruments(TM) F28379D microcontroller, and is based on the Configurable Logic Block (CLB) peripheral. This peripheral allows the configuration of custom logic operations without the need for external devices, such as Field-Programmable Gate Arrays (FPGAs) or other logical components. The validation of the proposed implementation is performed through a comparison between experimental hardware-in-the-loop (HIL) results and offline simulation results.
