Hysteresis Current Control Based Shunt Active Power Filter for Six Pulse Ac/Dc Converter

The series active filter works as sinusoidal current source in phase with the input voltage, drawing from utility sinusoidal and balanced input currents with low total

It consists of an electronic fast varying load based on a power MOSFET controlled by means of an innovative sweeping gate-source voltage in order to improve

Chandra, “ A new control philosophy for a unified power quality conditioner (UPQC) to coordinate load- reactive power demand between shunt and series inverters, ”

Thus, a single phase shunt active power filter with PI controller is used for reducing the current harmonics and voltage harmonics in the non-linear load. Single

- settling the PLL loop that is used to generate the sinusoidal reference, Fig.21. This event can last up to 0, 5 s depending on the initial conditions,

Finally a Simulink based model is proposed to reduce these harmonics from input current and hence to provide significant improvement in overall THD.The proposed methodology

Parallel (or shunt) active filters have been recognized as a valid solution to current harmonic and reactive power compensation of nonlinear loads. The principle of operation of

This paper discusses four different control strategies applied to shunt active power filter, the four control strategies are time-domain based strategies which are
