What are hysteresis current controller techniques for grid connected inverters?

Abstract: The purpose of this paper is to present a comparative study on basic hysteresis current controller techniques for grid connected inverters. Hysteresis current controllers are best known for robustness, fast error tracking, better dynamic response and ease of implementation than other controllers proposed in literature.

Can hysteresis current control be used in single-phase buck-boost grid-connected inverters?

The simulation results show that the proposed control method is able to transfer the desired current into grid successfully under all operating conditions. This paper presents a hysteresis current control for single-phase single-stage buck-boost grid-connected inverters.

Why is grid current not used in hysteresis control?

Since the filters have a delay effect on the inverter output current with all the ripples removed, the grid current (after the filters) cannot reflect the real value of the inverter output current so it cannot be used in hysteresis control. Therefore, the inverter output current before the filter is taken as the control target.

What is hysteresis control for three-level inverter?

Principle schematic of hysteresis control for three-level inverter. (dir / dt: the current rising slope; dif / dt: the current falling slope) The current path that flows from dc-side to ac-side is defined as a positive path (io > 0), and reversely the negative path (io < 0).
