Conventionally a single-phase to three-phase converter consists of a full-wave rectifier, dc-link capacitor, and six-switch three-phase inverter. The dc-link circuit only provides a fixed voltage to the six-switch inverter and the inverter is regulated by using the traditional sinusoidal-pulse-width-modulation (SPWM) method. This conventional single-phase to three-phase converter contributes higher current Total Harmonic Distortion (THD) compared to other types of three-phase converter. This paper innovates a single-phase to three-phase converter with a boost converter and regulates the six-switch inverter by using space-vector-pulse width-modulation (SVPWM) method. The boost converter enables voltage boosting and allows for the variable generation of DC input voltage to the inverter. The MATLAB/Simulink software is used to model and simulate the proposed converter. The output voltage and current at rectifier, boost converter, and inverter are analyzed to validate the design of the proposed converter. As a result, the suggested converter effectively produced a THD of 5.42% in the generated three-phase current. © 2024 IEEE.
