The MPPT algorithm is based on the calculation of the photovoltaic (PV) output power and the power change by sampling both the PV Array current and voltage Virtual Instrumentation (VI) is widely used in testing, measurement and control application as it is easy to understand and implement. Maximum power point tracking (MPPT) of solar array is demonstrated using a virtual instrument (VI) Find better angle with the help of INC. Voltage and current signals sensed from photo voltaic (PV) array are fed as input to the VI and control signal is obtained as output. The duty cycle of a buck converter which is placed between solar array and the load is controlled using the control signal. Incremental conductance (INC) algorithm is used for tracks maximum power.
