A contactless power transfer system for charging electric vehicles requires a high efficiency, a large air gap, and a good tolerance to lateral misalignment and needs to be compact and lightweight. A double-sided winding 10 kW transformer based on a 1.5 kW H-shaped core transformer was developed for a rapid charger. Even though the transformer capacity was increased, the dimensions of the 10 kW...
by Yang Zhang, M.S. Washington State University December 2007 Chair: Deukhyoun Heo This thesis presents novel designs of low-phase-noise 0.18μm CMOS LC voltage controlled oscillator (VCO) and quadrature VCO (QVCO) for 5-6GHz wireless communications applications. Using a new capacitor tapping technique, the phase noise of CMOS LC oscillators is lowered based on the improvement of loaded-Q improv...
An electrical probe is constructed of a small capacitor in contact with the circuit node under test so as not to load this circuit node and cause distortion of the input signal. The small capacitor is then placed in series with the small input resistance of a terminated coaxial signal line. The voltage signal at the output of the coaxial line will be approximately the product of the small capac...
Working standards for dissipation factor (D) obtained by connecting a shielded three-tenninal capacitor in series with a shielded precision resistor have been developed for calibration purposes. Precision conductance boxes have been built for use with a single three-tenninallOOO pF gas capacitor standard to create dissipation factor standards having values from 2 x 10-5 to 1 X 10-2. The design ...
