The Three-Carrier Quasi Switched Boost Inverter Control Technique [PDF]
Electronics, 2021 This paper presents a carrier modulation technique to control the three-phase, two-level quasi switched boost inverter. This PWM algorithm uses three carrier waves, the first of which is for the inverter while the others are for the booster. The boost factor depends on the short circuit interval on the DC/DC booster and the inverter.
