| Summary: | 碩士 === 國立中正大學 === 電機工程學系 === 86 === A circular chain control (CCC or 3C) strategy for multi-module
inverters in parallel operation to achieve an equal current
distribution is presented in the peper. In the proposed inverter
system, all the modules have the same controlconfiguration and
each modue includes inner current loop and outer voltageloop
controls. The PI controller is adopted as the inner current loop
controller toexpedite the dynamic response, and the H-infinite
robust control is adopted to reducethe interactive effect among
the inverters connected in parallel. With the 3Cstrategy, the
modules are in circular chain connection and each module has
anextra control to track the inductor current of its previous
module to achieve anequal current distribution. Simulation
results of a two-module and a three-module inverter systems with
different kinds of loads and with modulediscrepancy have
demonstrated the feasibility of the proposed control schemein
equal current distribution and fast regulation. Hardware
