Abstract :DC-DC power conversion can take three main forms in the sense of level conversion: buck insert ignore into journalissuearticles values(step-down);, boost insert ignore into journalissuearticles values(step-up); and buck-boost insert ignore into journalissuearticles values(step-up/down);. DC-DC power conversion from lower voltage value to a higher voltage value is called step-up application. A step-up application can be done with and without isolation. Non-isolated and isolated step-up power conversion can be achieved with different DC-DC converter topologies. In this paper, experimental verification of Output Inductor-less Phase-Shifted Full-Bridge insert ignore into journalissuearticles values(OIPSFB); DC/DC converter topology for constant current capacitor charging application is presented. The designed converter is able to charge an output capacitor to 700V DC. The charged capacitor can range from 1mF to 100mF. Experimental results are taken from a laboratory prototype with 24-36V DC input voltage range, maximum output power of 150W, switching frequency of 75 kHz and a digital average current mode controller. The results are for an output capacitor of 15 mF.
