Abstract :
In this paper, a new topology for high input voltage converter with input-series-output-parallel is presented. A key problem of this topology is the input voltage balancing. A voltage error between two inputs capacitor is sensed and controlled. An integrated-magnetic transformer is applied to realize the input voltage sharing. Three closed loops of output voltage, limited load current and input capacitor error are proposed. This configuration enables the usages of low rating voltage IGBT for a high input voltage system and the cost is lower. The performance of the proposed scheme is verified through the experimental results
