Abstract
In this paper, the focus is given on the implementation of a solar inverter with the use of STM32 and closed-loop communication. A power electronic switch is used to convert the voltage either into the grid or store it into a battery. In this topology, the STM Microcontroller has to control each and every function as per requirement, and advanced control algorithms are required to achieve control over each and every stage. For this closed-loop communication to control the switches, STM32 can interface with a CAN controller to easily communicate with the pulse width modulation (PWM) generation circuit. High-end PWM techniques control the analog voltage and convert it into binary digital form, which can be used to control the digital controller. High-end PWM increases the dynamic response to the control voltage change, improve efficiency, and have inner feedback loops and easy signal processing. By using sine wave pulse width modulation, we can generate the same sine voltage wave to control the inverters. Finally, power electronic switches can control each level of the sine wave into our desired output waveform and greatly reduce power loss.
