The voltage source inverter (VSI) is a commonly used power inverter. It converts a DC voltage into a three-phase AC voltage. So a three-phase inverter is required.
Three-phase topologies distribute current across three legs rather than two, reducing RMS current per switch by √3 for the same output power: versus single-phase: The reduced current stress allows three-phase inverters to achieve higher efficiency (typically 97-99%) compared to single-phase (94-97%) at power levels above 5kW.
This conversion is achieved through a power semiconductor switching topology. in this topology , gate signals are applied at 60-degree intervals to the power switches , creating the required 3-phase AC signal. This type of inverter commonly employed in conjunction with photovoltaic (PV) modules or the grid .
For the six switches of a three-phase inverter, there are only eight possible switch combinations, i.e., eight different switching states.
Our home solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment in Polish conditions. All systems include comprehensive monitoring and control with remote management capabilities.
