Characterization of GPS Antenna

Abstract: This paper presents Performance of VFD (Variable Frequency Drive) using FCCMLI (Flying Clamped Capacitor Multilevel Inverter). A conventional voltage source inverter-fed induction motor drive is modeled and simulated using matlab simulink and the results are presented. VFD using multilevel inverter is also simulated and the corresponding results are presented. The results obtained are compared. Using FCCMLI in VFD, Harmonics are reduced. Switching loss and EMI are also reduced.

Keywords: VFD, Problems of VFD, Multilevel Inverter, Modulation Technique, Simulation Circuits & Their results of VFD w ith Conventional Inverter & 3 level Inverter respectively, Analysis of THD.
