The growing application of lithium-ion batteries brings with it an increased risk of unanticipated energy releases and thermal runaway. Quantifying battery energy release characteristics during product design can help mitigate those risks.
Implementing a process of EMC compliance for a specific project is much more than simply ensuring that the design engineers follow a long list of “do’s and don’ts” in the form of EMC design rules. Following this process will reap benefits when EMC performance is evaluated at the end of the design process.
The selection of component values for common mode filters need not be a difficult and confusing process. The use of standard filter alignments can be utilized to achieve a relatively simple and straightforward design process, though such alignments may readily be modified to utilize pre-defined component values.
Secure facility designs often comingle ICS/ICD-705 and NSA 94-106 performance requirements creating project confusion with significant design and cost implications. This article focuses on bringing some clarity to the differences between ICS/ICD-705 design guidance and NSA 94-106 performance requirements. The related secure facility design and construction process is also reviewed.
Advance military and avionics technologies must be designed to address a range of complex specifications. The use of multiport connectors can provide significant benefits compared with conventional RF/microwave cable assemblies.
Low-frequency magnetic fields, a type of electromagnetic disturbance commonly found in electric vehicles, can pose potential health hazards to humans and affect the operation of critical EV components. Here are some design techniques to help mitigate the problem.
Values-based engineering is essential to ensuring that innovative products are based on ethical design considerations. The IEEE’s new standard, IEEE 7000-2021, provides a roadmap to help navigate this process and to help build trust in product designs.
The ubiquitous increase in the use of mains power switching devices has been paralleled by the increase in nuisance tripping of GFCIs and other protection devices. Nuisance tripping can be identified to contain such high frequency signals and these must be properly taken into account when designing proper GFCI operation in this environment.
Traditionally, validation engineers of analog products have had to worry about one thing, their analog function. But with the advent of functional safety, the complexity in system design has increased, and functions once found only in digital devices are now making their way into analog devices as well. This leaves individuals with one question- how to validate?
DC-DC converters are among the most important modules in an electric vehicle. In this article, we offer three recommendations to address design aspects of DC-DC converters that will make a huge difference in their EMC performance.
