This paper presents a control method for hybrid active power filter using Space Vector Pulse Width Modulation (SVPWM). In the proposed control method, the Active Power Filter (APF) reference voltage vector is generated instead of the reference current, and the desired APF output voltage is generated by SVPWM. A MATLAB code is developed to generate the SVPWM switching pulses fed to the two-level inverter...
A mathematical model of series-parallel compensation topology for contactless power transfer system is proposed in this paper. The effect of harmonics is considered to model the system parameter. A fourier series analysis is used in mathematical modeling. An experimental set-up of series-parallel compensated contactless power transfer system is built in the laboratory to verify the proposed model...
Reduced Voltage Source Multicell Converters are one of the best alternative for Capacitor Multicell Converter, as the former uses only a single voltage source as compared to the later which uses two voltage sources for a single phase converter. In this paper three different levels (i.e., 5 level, 7 level and 9 level) of reduced voltage source multicell converters are analyzed by taking THD as an analyzing...
Series-series (SS) compensation is widely used in contactless power transfer (CPT) for electric vehicle because of their constant current and constant voltage charging features. In this paper, a mathematical model of SS compensation for CPT system is presented. This model includes the effects of harmonics on parameters of SS compensated CPT system. Fourier series analysis is used for mathematical...
The magnetic flux density of an induction machine is a combination of space harmonics due to the fundamental magneto motive force and slot harmonics due to slots in both rotor and stator. Accurate determination of effects of slot harmonics on air-gap magnetic field is essential for analytical modeling of an induction machine. In the Literature, the relation to determine order of slot harmonics present...
For accurate determination of induction motor (IM) efficiency, precise knowledge of motor losses are required to be known. Stray loss constitute a part of the total loss and hence its detailed analysis and accurate determination is required. Classical IM theory and its equivalent circuit do not consider stray loss in it, resulting in inaccurate performance evaluation. In this work, analysis of the...
