The offline SMPS are efficient, lightweight widely used converters in consumer electronics connected to utility mains. Because of high-frequency switching, they produce conducted and radiated EMI also offering low power factor to the utility mains. The two issues involved in the SMPS are to increase the Power Factor and to mitigate the EMI, to comply with EMC standards. Techniques for reducing the...
In design of Near Unity Power Factor (NUPF) converter Electro Magnetic Interference (EMI) is a major problem. This paper provides an approach to minimize conducted EMI by incorporating EMI filter for the flyback NUPF converter. The poor designing of NUPF converter causes EMI noise which should be mitigated. Advances in computer aided design software and device models have enabled the simulation of...
This paper presents a bottom up approach for the peak load leveling of the Residential Distribution Feeder, by establishing local Microgrids. Which utilizes the sources within the Microgrid to reduce the dependence of the Distribution feeder on the maingrid during peak hours. The Microgrid presented here is mainly configured to use locally distributed Microenergy and Storage systems like Rooftop Solar...
Complex electronics devices are becoming more sensitive to electrostatic discharge (ESD). These components are being developed with higher density (extra memory bits per unit volume) and are becoming faster (MHz, GHz, THz, etc.). These upgrades in technology do not come without a ??technological price??. By enhancing the products' performance to meet the users' demands and requirements, one drawback...
A Transmission Line model of coupling is developed for determining the transient currents and voltages induced within aerial shielded coaxial cables by an impinging electromagnetic pulse generated by an Electrostatic Discharge (ESD) event. The Transmission Line theory is applied to establish the differential equations describing the behavior of the cables in the presence of a uniform plane traveling...
Electrostatic Discharge (ESD) generated Electromagnetic (EM) radiated fields can cause malfunctioning or upsets in an electronic system. This paper presents a mathematical computation of the effects of spatial electric fields from an ESD source. These fields may affect the normal functioning of an electronic system. This work uses a MATLAB program to model the response of Very High Frequency (VHF)...
