DN316 - Ultralow Noise Switching Power Supplies Simplify EMI Compliance
... frequency harmonics on the secondary winding are difficult to suppress. Even with an output filter inductor, the high frequency harmonics pass through the filter inductor to the output via the inductor’s parasitic capacitance. The best solution for attenuating the high frequency harmonics is to use ...

Introduction to Microwave Measurements, I
... The experiments in this lab fall into three main sections. In the first, we investigate the behavior and performance of "crystal" detectors (Schottky diodes) for detecting microwave power. The second part of the lab utilizes detectors of this type, along with the slotted line and standing wave meter ...

Wind Turbine Technology
... When the wind in the area increases above the cut in speed (3.5 m/s) the turbine blades are pitched from “feather” to “power” and the wind begins to turn and accelerate the rotor. Once the rotor achieves operational speed of 10-11 rpm the turbine is softly connected to the line with a ramp up of the ...

Utility frequency
The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the frequency of the oscillations of alternating current (AC) in an electric power grid transmitted from a power plant to the end-user. In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz. Current usage by country or region is given in the list of mains power around the world.During the development of commercial electric power systems in the late 19th and early 20th centuries, many different frequencies (and voltages) had been used. Large investment in equipment at one frequency made standardization a slow process. However, as of the turn of the 21st century, places that now use the 50 Hz frequency tend to use 220–240 V, and those that now use 60 Hz tend to use 100–127 V. Both frequencies coexist today (Japan uses both) with no great technical reason to prefer one over the other and no apparent desire for complete worldwide standardization.Unless specified by the manufacturer to operate on both 50 and 60 Hz, appliances may not operate efficiently or even safely if used on anything other than the intended frequency.
