A circuit that uses a programmable Arduino-based oscillator to generate a three-phase AC output is known as an Arduino three-phase inverter. In order to operate a specific three-phase load, we may learn how to build a basic Arduino-based microcontroller three-phase inverter circuit in the following section.
To go further One could then connect the 3 phase inverter to the grid and replace the DC power supply with a photovoltaic panel with a boost stage, to form a Three-phase PV inverter for grid-tied applications and showcase the great potential of imperix’s solution for modular power converters. Jessy is a power electronics engineer.
A three-phase inverter application uses six power switches (IGBTs in this case). To drive these switches, six totally independent gate drivers are required. Also, with a high-voltage operation, it is necessary to have enough isolation between primary and secondary side of the gate driver.
As we all know MOSFETs used in three-phase inverter circuits can be quite susceptible to damage due to various risky parameters that come into play with these concepts. This is especially true when dealing with inductive loads.
