This paper presents an adaptive hysteresis band current controller applied to hybrid power filters to compensate harmonics and the reactive power of a nonlinear load. This method changes the hysteresis bandwidth according to modulation frequency, supply voltage, dc capacitor voltage and slope of the reference compensator current wave. The hysteresis band(More)
Pulse width modulation controlled inverters produce Common-Mode Voltage (CMV), which is the main culprit of many system drawbacks ranging from Electromagnetic Interference (EMI) issues to bearing damage and insulation aging. Former methods for common-mode voltage reduction based on voltage control cause a great deal of extra harmonic distortion in output(More)
THD MINIMIZATION APPLIED DIRECTLY ON THE PHASE VOLTAGE OF MULTILEVEL INVERTERS BY USING ICA Adeleh Shahipour, Behrooz Vahidi, Javad Shokrolahi Moghani 1-Department of Electrical Engineering, Amirkabir University of Technology Tehran 1591634311, Iran * Corresponding author email: vahidi@aut.ac.ir ABSTRACT: Total harmonic distortion (THD) minimization is a(More)
With the increasing application of Induction Heating (IH) systems in various industries such as metallurgy, concerns about the harmonic effects and power quality of the power grid have been involved in the problems facing network operation engineers. This paper presents two methods to improve the power quality of three phase current source induction system.(More)
