This project arose from the need to develop experiments in power electronics during the Covid-19 pandemic. Experiments in power electronics generally require laboratories with expensive equipment and involve risks due to the level of voltage and power.
Considering the Texas Instruments kit BOOSTXL-3PHGANINV (https://www.ti.com/tool/BOOSTXL-3PHGANINV) kit, its three-phase bridge topology allows its use for several configurations of power converters, for example, buck-boost, single-phase, three-phase inverter.
An advantage of this kit, in addition to the three-phase bridge, is to have the current measurement at the output of each arm. Therefore, to expand the applications of this kit, it is enough to develop a plate with inductors and capacitors to configure the desired power converter. Another thing that is also necessary is the implementation of voltage measurement by means of a resistive divider.
Figure 1 shows the scheme of the prototype developed and video 1 shows a current control experiment in the single-phase inverter.
