Applications on STM32 Nucleo Microcontroller for Pulse Switching Using Time Delay and Trigonometric Function with MATLAB Simulink

This paper describes the development of single-phase rectifier with different switching technique for current feedback control using STM32F411RE microcontroller. This new type of microcontroller has been developed by ST company. Typically, this microcontroller only uses ST language to operate. But, in this paper, MATLAB Simulink tools proved that it can also be the programming language for this microcontroller. STM32F411RE was tested in rectifier application which included the special needs for the Pulse Width Modulation (PWM) switching algorithm to the converter such as time delay and trigonometric functions. For time delay application, the Proportional (P) control was used to control the current output and minimize the error for PWM signal. Meanwhile, the Proportional Integral (PI) control system was used for the trigonometric function, which also able to generate the PWM with time delay. It had been proved that the current can be controlled, and thus the rectifier using current control feedback was achieved through simulation and experimental verification by using this microcontroller.
