Research ArticleOpen accessPhrase in the titleReduced Order Models of a Current Source Inverter Induction Motor DriveIbrahim K. Al-AbbasProblem Statement: The current source inverter induction motor (CSI-IM) drive was widely used in various industries. The main disadvantage of this drive was nonlinearity and complexity. This work was done to develop a simple drive systems models. Approach: The MATLAB/SIMULINK software was used for system modeling. Three reduced models were developed by choosing specific frame, neglecting stator transients and ignoring … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,865 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign and Implementation of Closed Loop LCL-T Resonant DC-to-DC Converter Using Low Cost Embedded ControllerM. Annamalai, M. Vijaya KumarThe aim of this study is to simulate and implement open loop and closed loop controlled DC-DC converter for stand-alone wind energy system. Wind turbines, however, are not always very efficient in the wind speeds that are most common to a region. Typically, wind energy systems are designed to be highly efficient in high wind speed and have a cut-off … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 4 · 6 Feb 2013 · 7,589 accessesView PDF Cite

Research ArticleOpen accessIn the abstractElectromagnetic Interference Mitigation for Inverter fed AC DrivesC. Karthikeyan, K. DuraiswamyProblem statement: In switched mode PWM inverter EMI noise occurs during high (dv/dt) transient period. This EMI noise is mitigated using Active Common mode EMI filter in front of the source. Approach: This study proposes a new active common mode Electromagnetic Interference (EMI) filter for switched mode PWM Inverter applications. The proposed filter is based on current sensing and compensation … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 12 Sep 2011 · 7,309 accessesView PDF Cite
