The replacement of the disappearing incandescent lamps will be realized at a significant scale by compact fluorescent lamps (CFLs). Light regulation is a popular feature that is easily provided by incandescent lamps using a simple electronic equipment, the dimmer. Dimming can be achieved by (dimmable) CFL lamps as well, however this is done in a completely different way than in case of the form...

The paper is dealing with some electromagnetic compatibility (EMC) problems of converters and inverters, which are utilized for feeding of electric machines and its analyzing by PSPICE program. The main attention is focused on implications of parasitic capacitance and capacitive coupling existence.

The electromagnetic compatibility (EMC) community, usually concerned with noise and interference at the electronic-system level, has recently focused more attention on integrated circuits (ICs). This review concentrates upon the recent advances in microelectronics technology, the understanding of internal couplings within ICs, parasitic emission, and susceptibility to radiofrequency interferenc...

Electromagnetic compatibility (EMC) analysis of high-speed circuits is mandatory due to the rapid increase in operating frequencies, RF interference and PCB layout density. Radiated emission and immunity tests of electronic circuits and ICs are an important part of the overall EMC analysis and they have become a growing concern in prediction of an electronic system reliability. These tests are ...

Accurate driver and package models are necessary to analyze the signal integrity (SI) and electromagnetic compatibility (EMC) issues on digital circuits. 2-pole models that assume an ideal power distribution system (PDS) are commonly used in modeling the SI of signal lines. This assumption makes real SI and EMC analysis worthless or at least only useful under certain restrictions. In order to a...

This paper discusses the application of computational electromagnetics (CEM) for electromagnetic compatibility (EMC) problems of integrated circuits (ICs). It is known that the application of CEM is versatile in solving a wide range of problems. This paper focuses on the electromagnetic study of quad flat non-lead (QFN) packaged ICs, one monolithic microwave integrated circuit (MMIC) and anothe...

A computer-aided tool for the design of switching power supplies integrating layout editor, autorouter, component library builder, and EMI simulator is presented. The software takes on a modular approach and develops the printed circuit board (PCB) layout with emphasis on electromagnetic compatibility (EMC). The prediction of interference level is achieved by SPICE simulation with suitable mode...

This paper presents the design criteria, procedure and implementation of an AC-DC Flyback Switch Mode Power Supply (SMPS) which provides 250W rated average power to a big size Colour Television (CTV) Set with a DVD player. A novel technique is developed to keep the Stand-By power consumption of Flyback SMPS under 1W and a boost type of Active Power Factor Correction (Active PFC) preconverter is...

This paper presents novel active filter for mitigation electromagnetic interference (EMI) and other adverse effects of pulse width modulation (PWM) inverter-fed AC motor system. An active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects.
