A highly efficient, low cost photovoltaic water pumping system integrating a push-pull converter and a three-phase voltage source inverter using a single photovoltaic panel is proposed which has got high life time due to the absence of batteries. The converter steps up the panel voltage and the inverter powers the AC motors for varying speed conditions and it uses a sinusoidal pulse width modulation (SPWM) strategy with 1/6 optimal third harmonic injection. Maximum Power Point Tracking (MPPT) strategy forces the PV to extract the maximum power at the given irradiance level. The voltage reference obtained from this is used in a PI controller to adjust the motor speed. Thus the proposed pumping system works on varying power input and gives varying water output at a given pump head and can be used in isolated locations to deliver water.

2014 Conference Paper V. Vijayakumar, R. Divya, and A. Vivek, “Sliding mode controlled quadratic boost converter”, in International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC), 2014 , Chennai, 2014.[Abstract]

This paper deals with a quadratic boost converter which belongs to cascade boost family, controlled by sliding mode controller. In the cascade boost family, quadratic boost converter is the best trade-off when circuit complexity and modulator saturation is considered. Sliding mode control being a nonlinear control results in a robust and stable system when applied to switching converters which are inherently variable structured systems. The stability of this system is analysed through Lyapunov's approach. Analysis is done for load regulation, line regulation and step response of the system on Simulink model. Also these results are compared with that of PID controller based system.
