System Compatibility: An Essential Ingredient for Achieving Electromagnetic Compatibility and Power Quality for Lighting Control Systems
Philip Keebler, Kermit Phipps, Frank Sharp, EPRI Lighting Laboratory For years, lighting systems have been operating as stand-alone loads without the use of sophisticated lighting controls for energy savings in all types of facilities—residential, commercial, and industrial. Utilities and end users viewed lighting controls in the past as, luxury, systems that were used only … [Read more...]
Clocking Strategies for EMI Reduction
Sassan Tabatabaei, SiTime Corporation Electronic devices have to operate in close proximity, whether it is in the home, office, industrial establishment, or outdoors. Each of the devices may radiate electromagnetic energy, which can interfere with the operation of the rest of the devices. To avoid such harmful interference, governments and industry bodies limit the amount of … [Read more...]
EMC Performance of a Product Over Its Lifetime
Gert Gremmen, Tim Haynes, Ralph McDiarmid, Ed Price, John Woodgate EMC performance of a product is likely to vary with age as the physical characteristics change, e.g. caps dry out and metal junctions oxidize, etc. Obviously, the product is designed with the intention of consistent compliance over the life of the product, but are there any requirements or guidance relating to … [Read more...]
SuperH Microcontrollers with Built-In Large-Capacity 2.5MB SRAM
Because Renesas Electronics’ new 32-bit microcontrollers, the SH7268 and SH7269, have a large internal SRAM, there is no need for external memory, which saves power and space, increases performance, and lowers emissions of electromagnetic interference. The microcontrollers enable a smaller-size solution for digital car audio, consumer, and industrial applications, which drive a … [Read more...]

Living Life at 2.4GHz
In a recent article in Gizmodo discussing why 2.4GHz was chosen for unlicensed wireless items, attention focuses on the frequency of microwave ovens. The article notes that despite heavy shielding, microwave ovens’ powerful emissions could sometimes interfere with neighboring frequencies, so it was decided that they should be given a few megahertz of space in both … [Read more...]
