摘要

This paper presents a new adaptive hysteresis current control with unipolar pulse width modulation based on magnitude and time errors. Variable switching frequency due to fixed hysteresis hands is known as a drawback of hysteresis current control used in power system applications, which generates sub-harmonics and low order harmonics, and affects the quality of the power systems. Adaptive hysteresis band is a classical method to control the switching frequency. Several issues and solutions have been discussed and proposed in this paper to keep the switching frequency constant. Simulations have been carried out to verify the proposed adaptive hysteresis band controller and the results are discussed in this paper.
