This study introduces a novel nine switch converter topology for integration and power flow between hybrid Self-excited induction generator - Photovoltaic (SEIGPV)- based isolated system. The hybrid isolated system houses a 22-kW SEIG, an 18-kW photovoltaic system, and Battery Energy Storage System (BESS). Nine switch converter plays a vital role by providing continuous power supply irrespective of load or source side disturbances and helps in managing the power flow throughout the system. Two separate decoupled control strategies have been designed for source side and load side, which helps in regulating the voltage and frequency to be constant for both ends. The self-excited induction generator side power control strategy regulates the power flow and changes the DC-link voltage such that the excess/deficit power is stored/extracted from BESS. The whole system is subjected to two different loads, that is, linear load and dynamic load, and the uninterruptible power flow capability is also analyzed. The entire system has been simulated and modeled using Matrix Laboratory (MATLAB)-2018(a).
