Abstract
The Impedance Source based DC to AC or DC (Z-source DAD) converter converts the given DC voltage to AC or DC. In a solar photovoltaic (SPV) system, the solar panel output voltage is DC voltage, and this voltage will be converted to AC or DC by Z-source DAD converter. To get maximum output power from the panel, a modified perturb and observe (P&O) maximum power point technique (MPPT) is implemented with a Z-source DAD converter. This single-stage MPPT integrated Z-source DAD converter eliminates the conventional multi-stage SPV system, and also, the output voltage of this SPV system is either AC or DC voltage. The simulations are performed with MATLAB-Simulink software, and the hardware circuit is constructed with a microcontroller-based SPV system. The MATLAB-Simulink simulation and hardware output shows the ability of the modified P&O algorithm based MPPT integrated Z-source DAD converter.
