Conferences > 2023 IEEE International Futur... This project looks at the design and performance of a Three-phase inverter with a front-end SEPIC converter for grid-connected PV systems, using the power electronics software PLECS.
A PV inverter for large-scale installation usually comes in three-phase arrangements. The PV inverter combines the output of rows of PV strings in DC and converts them to AC. For example, an inverter can processes the output of a PV array with 500 PV modules. Three-phase output rated at 208 V or 480 V is commonly found in commercial PV inverters.
Three phase voltage source inverter (VSI) connects to the microgrid through an LCL low pass filter and operates either in current controlled (CC) or voltage controlled (VC) mode. Models presented here take into account the nonlinear behavior of the switches, delays in the control loops, and the practical constraints.
The two-stage DC to AC converter has an input voltage of 150V and is designed to have a single-phase voltage of 230V, three-phase voltage of 400V, power of 10kW per phase, and maximum efficiency.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
