In this paper, dual mode control is proposed for DC voltage regulation, generated through Photovoltaic (PV) energy and an interior point convex optimization based on quadratic programming algorithm is used to predict the optimal switching functions for all sectors of three phase inverter. It has been accomplished by minimizing a cost function which is defined for suppressing harmonics in output at each interval of sampling frequency. Optimized inputs are further used to generate a reference voltage signal, which is used for generating gate pulses of two level three phase inverter by Space vector modulation method. Discrete time model is used in order to feed the grid load. Furthermore Quadrature q-PLL technique is used for synchronization with utility grid. Simulations are carried out in Mat lab which validates the viability of the implemented controller. The simulation results proved that our proposed MPC-SVPWM technique has highly effective performance as compared to the linear conventional voltage source inverter techniques like sinusoidal PWM and SVPWM technique.
