Abstract

This paper presents a merged PWM-resonant dc-dc converter topology for localized PV energy harvesting. The topology merges a boost as the front-end converter and a series-resonant converter as the back-end converter. The two converters are merged by sharing the switches for their operation while they are decoupled by separating their control variables. Merging of the converters is facilitated by a control scheme that can change both the duty-ratio and switching frequency. The boost converter provides the ability to obtain MPPT control by changing the duty-ratio and the series-resonant converter allows for output voltage regulation by controlling the switching frequency. By merging the two power stages, high efficiency is achieved due to zero-voltage switching that is obtained on both switches and the component count is reduced. Full analysis and characteristics of the converter are detailed, and experimental results using a 400V/240W prototype validate its operation and features.
