systems which is employed to remove the current harmonics and compensate reactive
power. Hysteresis Current Control (HCC) is the simplest and fastest modulation
technique. The main issue in implementing the Fixed Band Hysteresis Current
Control (FBHCC) in APFs is its variable switching frequency results in increasing
the switching losses and acoustic noise as well as injecting vast range of high
frequency harmonics into the system current waveform. To avoid this situation,
Adaptive HCC (AHCC) methods with the variable hysteresis bands have been recommended
in literature. The AHCC can fix the switching frequency and remedy the mentioned
problems significantly. In this study a simpler equation has been proposed to
calculate the value of adaptive hysteresis bandwidth instantaneously. The proposed
method reduces the size of calculation in controller which makes it response
faster while shows the proper results in harmonics elimination and decreasing
switching losses. The simulations have been done to validate the efficiency
of this method by Matlab/Simulink.]]>Akagi, H., Y. Kanazawa and A. Nabae,1984IA-20625630Bose, B.K.,199037402408Emadi, A., A. Nasiri and S.B. Bekarov,2005Pages: 276Pages: 276Kazmierkowski, M.P., R.
