DC to AC Converter for Active Filter Based on STM Discovery Platform

The methods of designing power electronic devices have been studied. DC to AC Converter was designed on the STM32F4 Discovery debug board. The device includes a control system, power amplifiers, short circuit protection and power switches. A low power transformer is provided to convert voltage levels. The controller software was developed using the MATLAB / Simulink software package, and the board was debugged and flashed. Comparison of the stability of the device and the quality of the generated signal at different carrier frequencies is made. The data obtained from the operation of the device made it possible to assess the build quality and determine the scope of application of the developed device. The device is capable of generating a signal of a given frequency and amplitude, including interharmonic components, which allows it to be used as an active current filter for low power supply systems.
