The simple embedded system for three-phase solar motor pump using Volt/Hertz maximum power point tracking technique

This paper presents the research and development on the embedded system for three-phase solar motor pump with the Volts/Hertz (V/F) maximum power point tracking technique (MPPT) which significantly simplifies the software design complexity for PWM three-phase motor drive inverter. The software of the control system and MPPT is designed by using the microcontroller to generate the command signals for MC3PHAC chip. The experimental results show that the maximum power adjusted by the proposed system on the variation of the sunlight intensity is very close to that of the reference system. We also show the characteristics of the maximum power point tracking of the PV Array. Our design of this system can be applied and developed on many other purposes. In addition, by using our proposed software design, the implementation is simple and inexpensive.
