摘要: Recent research and industrial accomplishment has revealed the advantages of cascaded smart converter Photovoltaic (PV) system over traditional centralized string PV system. However, normally higher cost than central-level or string-level MPPT due to fact that each need individual controller, voltage current sensors. In order solve this problem, a multi-phase with single controller is proposed in paper. Comparing converter, solution can largely reduce by saving controllers, sensors without sacrificing energy production. The effectiveness structure verified both simulation hardware testing. also be extended work as subpanel-level converters.
