In this work a Current Injection technique has been introduced to mitigate Current Harmonics and to improve Power factor present in a high power Converter system. This work proposes the simultaneous Current Injection in all of the three phases. Current Injection technique has to be performed with the help of a Injection Networks and Injection Devices. A Passive Resistance Emulator is used to adjust...
This paper studies experimentally the harmonic distortion and the methods to mitigate the harmonics for a 6 KVA UPS system. Phase Locked Loop (PLL) based passive power filters are designed to reduce harmonic distortion and to correct the power factor. The proposed method minimizes the designed filters total investment cost such that the harmonic distortion reduced. In a real time 6KVA UPS system,...
