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
