In this article, a novel structure for four-switch three-phase inverter with the ability of creating null vector is proposed. This utilizes symmetrical quasi-Z-source network and generates zero output voltage during shoot-through state, which similar to in conventional six-switch inverter. used remaining time each switching period. means that proposed has several advantages over inverter, two a...

This paper proposes a new family of discontinuous PWM strategies to control the quasi-Z-source nine-switch inverters (qZS-NSI). The presented provide buck and boost inversion capabilities, suitable for common-frequency different-frequency modes operation. Accordingly, two different shoot-through (ST) approaches are introduced compared. first approach uses three-leg ST, while second single-leg S...

This paper proposes a novel electrolytic-free quasi-Z-Source Ćuk LED driver for automotive applications. Compared to the traditional converter, first merit of converter is higher gain, which makes it apt switch between multiple Secondly, proposed combines inherent characteristics load operate in wide range Continuous Conduction Mode (CCM), so inductors can assist energy storage, and only small ...
