This paper presents a control strategy for input-parallel–output-parallel (IPOP) connected modular inverter systems. Each modular inverter is composed of a high-frequency isolated dc/dc converter followed by a dc–ac inverter. The control objective of the configuration is to achieve output current sharing among the constituent modules and also can suppress the circulating current among them successfully...
Input -series connected DC/DC converters based on one transformer is proposed for high voltage input and high power applications. Phase-shifted full-bridge (PS-FB) control strategy with common duty cycle control is adopted for each converter. Operation principles of the proposed converter are analyzed. Although primary currents vary for magnetic coupling and turns mismatch, combined peak current control...
