A study of solutions to EMI of computer monitoring and control system in hydropower plant
Tập 2 - Trang 716-720 vol.2
Hydropower plant is a large energy conversion location, which suffers strong EMI. Its computer monitoring and control system works under a bad electromagnetic environment. Aiming at raising its ability against EMI, this paper makes a study on the solutions with the applications of some basic EMC techniques. The generator busbar, primary device, auxiliary equipment and transmission line are discuss......

Decoupling strategies for printed circuit boards without power planes
Tập 1 - Trang 258-261 vol.1
Traditional decoupling capacitors connected between V/sub CC/ and GND traces can be relatively ineffective at frequencies above their self-resonant frequency. This paper evaluates decoupling capacitor mounting strategies on boards without power planes. Techniques for minimizing mutual inductance and improving decoupling at frequencies above resonance are investigated.

Nonorthogonal PEEC formulation for time and frequency domain modeling
Tập 1 - Trang 452-456 vol.1
Electromagnetic solvers based on the partial element equivalent circuit (PEEC) approach have proven to be well suited for the solution of combined circuit and EM problems. Most of these tools have been based on rectangular or Manhattan geometries. In this paper we extend the PEEC formulation to the case of nonorthogonal geometries since many practical EMC problems require a more general formulatio......

The use of via holes for controlling the crosstalk of nonparallel microstrip lines on PCBs
Tập 2 - Trang 633-638 vol.2
In this work, the metal filled via holes are constructed into fences between the nonparallel microstrip lines to control the crosstalk. In practice, coupling between nonparallel traces is common. On the other hand, via holes are easy and inexpensive to build using the current fabrication process for the commonly used PCBs. The effects of the via holes for alleviating the coupling are investigated ......

ESD currents and fields on the VCP and the HCP modeled using quasi-static approximations
Tập 1 - Trang 81-86 vol.1
The horizontal coupling plane (HCP) and the vertical coupling plane (VCP) are essential elements of the standardized electrostatic discharge (ESD) test. They are used for testing the robustness of equipment against indirect (nearby) discharges. This article analyzed the current and the fields on the HCP and the VCP using plane wave, transmission line, quasi-static theory. The objective is to illus......

RF emissions certification for large systems: a risk-management approach
Tập 2 - Trang 772-777 vol.2
A method is presented for demonstrating the compliance of the radiated emissions of a system composed of commercial off the shelf (COTS) apparatus with the requirements of the European Electromagnetic Compatibility (EMC) Directive (89/336/EEC - EMC). The method is an alternative to performing practical emissions measurements and converts the compliance process from a simple pass-fail to a risk-ana......
