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.

A PWM Scheme for a Fault-Tolerant Three-Level Quasi-Switched Boost T-Type Inverter [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 In this paper, a new optimal pulsewidth modulation (PWM) scheme for a three-level quasi-switched boost T-type inverter (TL qSBT 2I) under normal and failure modes is proposed. The proposed method reveals its semiconductor fault tolerance capability in open-circuit fault condition situations as described in this paper.
