Shunt active power filter is suitable to compensate current-type harmonics generated by nonlinear load. However which generates high frequency switching harmonic current into the power grid by using the pulse width modulation (PWM) technology. So the switching harmonic filter must be used to eliminate ripple current. Based on the analysis of the working principle of switching harmonic filter, the...
This paper analyzes the compensation performance of a shunt hybrid active power filter. The hybrid active power filter, which combines passive filter and active power filter, has both respective merits, and is an important developing trend of filtering device. The hybrid active power filter can reduce the capacity of active power filter effectively and is more suitable for the engineering application...
The study of a fuzzy logic controlled, three-phase shunt active power filter to improve power quality by compensating harmonics and reactive power is presented. The advantage of fuzzy controller with self-adjustable factor proposed in this paper is that it is based on a linguistic description and does not require a mathematical model of the system. Furthermore the fuzzy control rules can be modified...

Shunt hybrid power filter has been proved to be a useful approach to eliminate current harmonics caused by nonlinear loads. The passive power filter suppresses harmonic currents produced by the load, whereas the active power filter improves filtering characteristics of the passive filter. Nowadays, the passive filter has many kinds of topologies. Among them, the single tuned passive filter has gained...
