چکیده

A three-phase multi-level multi-input power converter topology is presented for grid-connected applications. It encompasses a transformer that operated on the primary side in an open-end winding configuration. Thus, supplied one by N-level neutral point clamped inverter and, other side, auxiliary two-level inverter. key feature of proposed approach able to perform independent management N ? 1 input sources, thus avoiding need additional dc/dc converters hybrid multi-source systems. Moreover, it can manage energy storage system connected dc-bus The operates at low switching frequency and be equipped with very on-state voltage drop Insulated-Gate Bipolar Transistor (IGBT) devices, while instead according conventional high-frequency Pulse Width Modulation (PWM) technique resistance Metal-Oxide-Semiconductor Field-Effect (MOSFET) devices. Simulations experimental results confirm effectiveness its good performance terms grid current harmonic content overall efficiency.
