A multilevel modular DC-DC power conversion topology based on cascaded H-Bridge
converters in a double П configuration is presented. The topology is intended to interconnect
large power DC networks. A two level control hierarchy is used to regulate the DC voltage of
each H-bridge module. At the top level, DC and circulating AC currents are used to control the
total energy converter in all branches (both parallels and series) of each П arrange. At bottom
level, the voltage balance of a converter branch, which comprises N H-bridge modules, is carried
out by balancing (N-1) capacitor voltage deviations, with respect to the average capacitor
voltage. The entire topology and control strategies are simulated in a PSIM environment.
Simulation results with three H-bridge converters per branch are shown and preliminary
experimental results with a low power prototype are also included. [-]
