2. Digital software solutions

2.1 Generic microcontroller structure

Software-based digital solutions have predefined hardware architectures, and the user only acts through programming and configuration of the hardware part, using programming languages such as C, C++, Java... For the purposes of this article, we will focus on microcontroller-based digital software solutions, as these are the most widely used for controlling power electronics converters. As shown in figure 2 , a microcontroller is defined as an integrated circuit that combines :

• a processor that executes instructions. The processor runs at a system clock speed which determines how fast it can execute tasks;...
