SiC MOSFET and IGBT Hybrid Shunt Active Filter and its Application on a 10 KVA Harmonic Load System
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2020, Vol 4, Issue 5
Abstract
This paper introduces a energy efficient, cost effective hybrid shunt active filter SAF concept and it application on a 10 kVA harmonic load system, with current harmonic rejection capability compared to IGBT based SAF solutions. Normally, IGBT based Shunt Active Filter designs face difficulty in higher order harmonics mitigations due to restricted switching frequency of operation typically limited to 10 kHz . In this paper, a hybrid shunt active filter HSAF solution is introduced where one IGBT based inverter removes lower order harmonics 5th and 7th and a SiC MOSFET based inverter removes the other higher order harmonics 11th, 13th… . The IGBT is rated for 90 of the total load kVA rating but is switched at 5 kHz switching frequency. On the other hand, SiC MOSFET based inverter is rated for a small percentage of total kVA load but is switched at 30 kHz to remove the higher order harmonics more effectively. The introduced concept is verified by simulation results. Abhilash Bhattacharjee | Prof. Sharath.
