Input Series-Output Parallel Connected Converter for High Voltage Power Conversion Applications Employing Charge Control

In this paper, the charge control with the input voltage feed forward is proposed for the input series-output parallel connected converter configuration for high-voltage power conversion applications. This control scheme accomplishes the output current sharing for the output-parallel connected modules as well as the input voltage sharing for the input-series connected modules for all operating conditions including the transients. It also offers the robustness for the input voltage sharing control according to the component value mismatches among the modules.
