The standalone solar photovoltaic (PV) powered water pumping system could have either two power conditioning units (PCUs) or a single PCU. The system with single PCU is advantageous over the prior because of low device count, smaller in size, low cost, low losses, and higher efficiency. This chapter includes four such single-stage PV water pumping systems. All the four systems are operated using the integrated control technique which assimilates maximum power point tracking (MPPT), pulse width modulation (PWM) technique, and motor control. But the PV systems differ in the inverter configuration used as well as the employed induction motor (conventional star connected and open-end winding induction motor [OEWIM]). The detailed description of mathematical modeling, design and analysis of all the four PV pumping systems along with the simulation results are presented in this chapter.

A new control strategy to extend the unbalanced operation of the induction motor driven system based on a single-phase electronic power transformer (EPT) is proposed in this paper. This new motor driven system avoids the traditional input power transformer and only single-phase power network is needed. It has a modular structure and consists of series H-bridges rectifier, output-parallel dual active bridge converters and a three-phase voltage source inverter. In the input stage, a new control strategy is proposed to balance the dc voltages among the series H-bridges and regulate the current. This new control algorithm determines the minimal reactive current to stabilize the converter when the loads are seriously unbalanced. In order to verify the new driven system, a 3 kV/462 V/180 kW EPT driving an induction motor is constructed in MATLAB/SIMULINK. The simulations results illustrate the effectiveness of the proposed unbalanced control algorithm and good dynamic behavior of the integrated control system for this new driven system.
