Boost Inverter Fed Three Phase Induction Motor for Off Grid PV Based Water Pumping System

This article presents the development of a three-phase inverter of medium power used in pumping system photovoltaic autonomous, that solves the needs of high consumption of energy in populations away from the national electrical network, whose final application is the use in the agricultural sector. Considering that this application uses an induction motor as a load, it is common to oversize components in such a way that they can withstand the starting current of this, which leads to a negative impact on the volume and cost of the system. This is the reason why it is emphasized the importance of the design with the main objective of selecting the appropriate components for a system, avoiding oversizing. The above is carried out through the implementation of the Sinusoidal Pulse Width Modulation (SPWM) modulation technique operating under the constant torque operation regime. To check the proper operation of the constant torque regime, a comparison with the constant voltage regime is carried out. In addition to the above, the easy implementation of the modulation under the different operating regimes is highlighted by means of the direct link between Matlab/Simulink® and the NUCLEO STM32F767 microcontroller.

“…Integrating extra topology causes the cost to rise, reliability to drop, and system lifetime to suffer. Singh et al [23] and Barwar et al [24] make use of control techniques such as DTC in combination with current tracking to minimize the starting current, increasing the complexity of the system.…”
