A Simple and Cheap Method of Rapidly Prototyping Power Electronic Converters using Microcontroller

Nikunj Kumar Agarwal, Sandeep Banerjee, Sidharth Talia, Komal Bagai


This paper shows the study and research done on the design strategy of single phase sinusoidal pulse width modulation (SPWM) waveform. STM32F103C8T6 microcontroller, a part of STM32F103X series, is used for this purpose. Arduino IDE, an open source platform is used for developing the firmware for the SPWM signal generation on the STM32F103C8T6 microcontroller. This is an inexpensive microcontroller that can generate a perfect SPWM waveform of any desired frequency. The method aims at reducing the cost of digital control signal generators while also allowing engineers to use high level, open source programming methods to expand the capabilities of their device.
