چکیده

In this paper, a hysteresis current control technique for a single-phase five-level inverter with cascaded H-bridge topology is proposed. The basic study to implement the logic for correct voltage-level selection, various schemes available in the literature have been described and will provide a useful framework and point of reference for the future development of hysteresis modulation for multilevel converters. By using the recently developed multilevel hysteresis modulation approaches, the advantages of using several accessible dc potentials in a multilevel inverter have been fully exploited. All of these hysteresis modulation approaches are tested for tracking a current reference when applied to a five-level inverter.

Modeling & Simulation of Hysteresis Current Controlled Inverters Using MATLAB

Hysteresis inverters are used in many low and medium voltage utility applications when the inverter line current is required to track a sinusoidal reference within a specified error margin. Line harmonic generation from those inverters depends principally on the particular switching pattern applied to the valves. The switching pattern of hysteresis inverters is produced through line current fee...
