Quasi-switched inverter using space vector pulse width modulation with triangular comparison for photovoltaic applications [PDF]
TecnoLógicas, 2018 This work analyzes a prototype of a quasi-switched boost inverter (qSBI) feeding an isolated resistive load from a DC source. The use of spatial vector pulse width modulation (SPWM) with triangular comparison is proposed to increase the qSBI gain factor,

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.

DC-Link Quasi-Switched Boost Inverter With Improved PWM Strategy and its Comparative Evaluation
IEEE Access, 2020 Low voltage stress on the impedance source network devices is the main reason for the advent of DC-linked type quasi-switched boost inverters (DqSBIs). However, the DqSBI has become less attractive due to its low voltage gain. This paper presents a novel
