Abstract
In this paper, a charge control with an input voltage feedforward
is proposed for an input-series-output-parallel-connected converter
configuration for the high-speed-train power system application. 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. This configuration enables the usage of a MOSFET for
a high-voltage system allowing a higher switching frequency for a
lighter system weight and smaller size. The performance of the proposed
scheme is verified through the experimental results
