Power Quality Improvement using Shunt Active Power Filter with PI and PID Controller
Problems caused by power quality have great adverse economical impact on the utilities and customers. Current harmonics are one of the most common power quality problems and are usually resolved by the use of shunt passive or active lters. In this paper we have compared the THD values of Shunt active power filter with PI […]
Power Quality Improvement using Shunt Active Power Filter
Nowadays, usage of non linear loads in power system is increasing. For example, UPS, inverters, converters, etc. These loads make the supply current non sinusoidal and distorted form, which is called harmonics. At this time Active power filters have been developed to improve power quality. In this Paper, a Shunt Active Power Filter SAPF control […]
Power Quality Enhancement using DSTATCOM by Immune Feedback Control Algorithm
This paper proposes an immune feedback control algorithm for a three phase distribution static compensator DSTATCOM to mitigate several power quality problems such as harmonics, reactive power, and load unbalancing at distribution level. This control algorithm proposed for DSTATCOM, is validated for maintaining power factor to unity, load balancing, and harmonics reduction of supply currents. […]

Harmonics Reduction And Power Factor Improvement of Switch Mode Power Supply By Using Zeta Converter IJTSRD
This article describes the topology of a DC DC converter operating in switching mode on off . During the completion of the switching cycle, the entire current flow may be resolved and the load may be left. Under these conditions, the initial conventional upconverter switches are heavily loaded and result in large power losses. Switches […]
