This study explains the operation and design of Landsman DC-DC converter employing
maximum power point tracking (MPPT) controller for maximum power conversion in a solar
Photovoltaic (PV) array. The output DC voltage of converter through inverter is fed to the
induction motor based water pump. The above system is proposed by using a neutral point
clamped (NPC) multilevel inverter for the DC to AC conversion. Incremental conductance
algorithm is chosen to operate the PV array close to optimum operating point. The input
voltage and current is sensed to achieve MPP. Output voltage is sensed to get required
regulated output voltage. The controller is designed to obtain the regulated output at
different load and irradiance conditions. The overall proposed system is simulated and the
THD analysis is done for the output voltage of the inverter.
