Design and Development of INC-MPPT Switched ZETA Converter for Solar PV Arrays

In this paper, an improved zeta converter is designed, its performance was studied by simulation and a hardware prototype was developed to validate its results. The designed zeta converter is gated by switching signals from a controller running Incremental Conductance - Maximum Power Point Tracking algorithm (INC MPPT) which aids in mining out the ceiling power from the PV array. Also, a voltage source inverter (VSI), controls and drive the motor and uses a fundamental frequency switching without current sensors. The proposed design of improved Zeta converter is custom designed for a PV array whose power is used to drive a water pump. The stability and performance of the proposed system are demonstrated through simulation results followed by an experimental validation through a hardware prototype.
