基于N相交错有源前端升压级的阻抗源逆变器PWM控制

Non-isolated high gain inverters, such as impedance source inverters (ZSI), are suitable for applications with limited input dc source voltage, e.g., microinverters. High gain in these inverters is attributed to the front-end boost stage (FBS). High step-up ratio results in very high input current as the power rating of the inverter goes up. This leads to significant conduction loss in the non ide...
