The Inertial Energy Control Strategy of the Cascade H-Bridge Module applied in Photovoltaic System

This paper put forward the inertial control strategy based on of charge and discharge supercapacitor trigger angle H-bridge which integrates photovoltaic (PV) system. The whole cascade structure is composed traditional module, Boost/Buck circuit, (SC), circuit. First, charging state energy power support SC are analysed. Then proposed. To verify efficiency strategy, a chain consists 12 unit was built in EMTP simulation software. Finally results prove that newly developed SC-integrated module can do well, important to coordination between system solar energy.
