Interactions Between Electromagnetic Compatibility, Mutual Parasitics, and Filter Performance

Interactions Between Electromagnetic Compatibility, Mutual Parasitics, and Filter Performance
The application of electromagnetic compatibility engineering can be used in many diverse fields. There are many ways to use this engineering discipline including: electrical and electronic equipment manufacture, installation, and communications. This type of engineering is used to examine the electrical and electronic systems in a product or manufacturing process to make sure they will work well together and perform their function safely. A certified electrical and electronic systems engineer is trained and certified in the application of electromagnetic compatibility engineering.

Senior power electronics systems engineer for low voltage power electronics and distribution systems. Electromagnetic compatibility engineer to suppress power line noise on alternating current and high frequency power electronics. Specialist electrical and electronic systems engineer who is also a licensed systems engineer to test power supplies, transformers, fuses, and safety relays for maximum productivity and efficiency. Also, this individual may be required to inspect and install electrical and electronic components of high frequency alternating power systems.

In the past, the University of California, Los Angeles, was one of the major schools to teach the study of electromagnetic compatibility. Other universities that have specialized in the field of EMC are Arizona State University, Northern Arizona University, and the Massachusetts Institute of Technology. Currently there are several university departments that specialize in the application of EMC to various industries including communications, personal electronics, automotive, military, and healthcare. Electromagnetic Compatibility has been studied and applied for over 50 years. Current research interests include computer generated electromagnetic interferences, sound waves, opto-electronics, wireless technologies, and solid state electronics.

The Department of Defense is currently working toward developing advanced electromagnetic weapons. Military technologies have been the subject of much research and the development of new weapons by all branches of the armed services has been a joint effort. One branch of the military that has developed and used this technology is the United States Navy. There are also numerous military exercises and other drills that use this technology.

It is important for businesses to understand the current studies and applications of electromagnetic compatibility, especially considering how the growth of the Internet will impact our world and the security of our nation. If you are involved in the design of electronic products and/or the development of computer systems for use with these products, you should be aware of the modeling strategies and practices that are being utilized in the defense industry. Additionally, if you are a business involved in transgene telephone systems or you are a provider of space based telecommunication systems you should also be familiar with the modeling strategies and practices being utilized for mitigating electromagnetic interference.

There are a number of ways to model the interaction of electromagnetic systems within a given environment. There are two basic modeling strategies and processes that have been proposed to explain the behavior of electromagnetic systems: Filter Function and Filter Optimization. A filter function attempts to describe a system by the sum of its individual filters. A high-order filter, for instance, might describe a system that is intended to remove all microwave frequencies above a certain frequency range while a low order filter might describe a system that is intended to only remove frequencies lower than a certain frequency range.

A Filter Optimization technique attempts to describe a system by the operation of various filter functions that are designed to achieve some specified objectives. Some of these objectives might be to prevent microwave radiation from penetrating an object while others might be to reduce or remove the power of the microwave signal. One example of a filter optimization process might be to ensure that an alternating current source provides the maximum voltage swing needed to drive a power electronic device. However, it could also be to minimize the overall amount of energy absorbed by an electrical device in order to provide the lowest possible power electronic output.

Based on this information, it would be clear to see how the mutual parasitics functions are interlinked. The mutual parasitics is designed to minimize power consumption. Thus, the overall performance of the power electronic device is improved. On the other hand, the overall filter design was improved to improve filter performance.
