摘要: It is highly essential to develop a control technique that can be applied conventional two-level as well high-power multilevel front-end converters (FECs). Multiaxis current controlled, unity power factor (PF), regenerative FEC described in this article. Current error space phasor controlled by multiaxis monitoring and its movement confined within the prescribed hexagonal boundary. shown needed information on sector change detection derived from instantaneous values of supply voltages for FECs. However, similar approach cannot extended three-level Hence, employing additional outer hysteresis band proposed. With help experimental results, steady state dynamic conditions FEC, it demonstrated proposed current-controlled equally applicable A flying capacitor topology considered, where voltage balancing capacitors guaranteed effective utilization redundant switching states. Results clearly depict system friendly nature presented scheme, i.e., PF, low total-harmonic distortion current, good load line regulations, with capability converter. All schemes are implemented OPAL-RT hardware-in-loop platform.
