Wireless Space Vector Pulse Width Modulation Control of Three-Phase Inverter Using RF-link

This paper discusses the conception of wireless structure for the implementation of space vector pulse width modulation using a microcontroller ATmega 2560 to control a tow level three-phase inverter in order to establish a wireless link at less information and energy losses at real time and to attend a wide range of distance. The principle of this study is the ability to control an inverter using a Radio Frequency link and compare its performance under dynamic and stable conditions with those obtained using wired communication. Traditionally there are different types of processors that were used to implement SVPWM such as Microcontrollers, Microprocessors, dsPICs, and DSP. However its moderate processing and complex interfacing with an RF-link which makes the ATmega 2560 one of the best choices to reduce the computation time and to ease the implementation. The Experiment results show the ability of our system to generate three PWM signals corresponding to the SVPWM and establish a wireless communication through RF-link successfully.
