Hysteresis current control with distributed shoot‐through states for impedance source inverters

Summary This paper presents a hysteresis current control technique with shoot‐through states distribution. This control algorithm could be applied to three‐level and multi‐level inverters with any impedance source network where reference current control signal along with shoot‐through states are required. Possible modifications of the presented algorithm are discussed. The steady‐state analysis was made to explain the operation principle of the algorithm. As a result, the link between the band ratio of the hysteresis current controller, the input voltage, and the desired DC‐link voltage was obtained. All theoretical predictions were proved by simulation and experimental results. Future applications are discussed.
