Inverters and loads can freely connect to any node in a meshed parallel inverters system, leading to variations of line impedance between two nodes and the structure of the electric network. More challenges exist for proportional load-sharing control in such a system. An improved proportional load-sharing strategy for a meshed parallel inverters system with complex impedances is proposed in this paper...
Three-phase inverter has been widely applied in various applications, and lots of control schemes are investigated for the inverter powering nonlinear load, aiming to achieve favorable performance. However, the model currently proposed for inverter is based on linear load, which is not suitable for condition with nonlinear load. In this paper, a novel modeling method for three-phase inverter powering...
An improved switching loss calculation method for IGBT switching on, switching off and the diode reverse recovery energy losses in neutral point clamped inverter is proposed in this paper. A model of linear instantaneous switching on and off waveforms is presented to approximate actual switching process. The IGBT switching on and off duration, the changing rates of current di/dt and collector-emitter...
