This paper presents a newly developed 24 V / 3.5 kW output two-stage ac-dc power supply for battery charge application. In this developed two-stage structure, 400 V three-phase three-level T-type PFC ac-dc input stage is followed by an isolated dc-dc buck converter as an output stage. The combination of SiC Schottky Barrier Diodes (SBDs) and Super Junction (SJ) MOSFETs are employed for input stage...
In this paper, the one-comparator counter-based pulsewidth-modulated (PWM) control strategy without any analog-to-digital converter (ADC), used in the DC-DC converter, is applied to the DC-AC converter with some modifications. In addition, the voltage reference feedforward control is applied so as to reduce the burden of the proportional integral derivative (PID) controller. Via some experimental...
This paper proposes a novel step-up DC/DC converter with galvanic isolation - the quasi-Z-source inverter (qZSI) based DC/DC converter and discusses three different shoot-through PWM control methods suitable for this topology. The proposed converter is meant for applications where the wide range of voltage gain is demanded, e.g. with renewable energy sources (fuel cells, photovoltaic cells), in telecom,...
