This paper presents the capability of Arduino for responding to the robust controller which has been applied to the 3 phase rectifier and 3 phase inverter. The interface between the converters and the Arduino has been established by using MATLAB-Simulink environment. This is the fastest interface due the Arduino library that is available in the MATLAB which can be used before downloading the program to the board. Two types of controllers have been tested which are, P-Resonant and Fuzzy-PI controller. The voltage or current feedback mechanism also has been applied between the converters with the Arduino input port in order for responding to the design controller for signal generating pattern. At the end, it shows that, the Arduino is capable to receive the signals from the converters, process the signals in the board and generating the signal out for controlling the converters.

This paper focuses on investigation of various voltage controllers which are the Proportional Integration Derivative (PID) control and P-Resonant control in order to observe the efficiency of the low cost microcontroller such as Arduino for the gating signals generation. Both of the controllers have been selected due to the availabality of the block diagrams that can be build in the MATLAB. The MATLAB-Simulink block will be used as the interface between the design controller to the Arduino board before downloaded into Arduino. The results show, the Arduino is able to operate from various controllers but it gives better result when the P-Resonant controller has been used.
