Abstract:
This project was a step forward in investigating the effect of supply voltage harmonic contents on the measured leakage current of polluted insulators operating in different environments. This study was then used as a basis for developing a sound theoretical understanding of the effects of supply voltage harmonic contents on the measured leakage current characteristics. This study was also used to develop a new condition monitoring index for the polluted insulator under harmonically distorted supply voltage.

Abstract:
In recent years, the demand for Li-ion-type batteries has been increasing significantly in various fields of applications including portable electronics, electric vehicles, and also in renewable energy support. These applications ask for a highly efficient charging strategy in order to maintain a long life cycle of the batteries. Recently, a new charging technique referred as sinusoidal ripple current-constant voltage charging (SRC-CV) technique has been proposed and is in certain publications claimed to realize an improved charging per-formance on Li-ion batteries than conventional constant-c

Abstract:
In variable speed motor drive and uninterruptible power supply (UPS) applications, taditional method is to employ some kind of a modulation technique at a high frequency typically 6 kHz to 20 kHz range. In these modulation techniques, the switches are hard switched. The result is application of a series of pulses to the load, and if the load is inductive, sine wave current flows into the load. Hard and rapid switching causes a voltage waveform with a very high dv/dt (rate of change in voltage) causing high EMI problems, reduced life expectancy of the motor and additional losses.
