Voltage/Current Doubler Converter for Electric Vehicle Wireless Charging Employing Bipolar Pads

Light-duty electric vehicles (EVs) typically have a rated voltage of either 400 or 800 V. Especially when considering public parking infrastructures or owners with multiple EVs, e.g., car rental companies, EV wireless chargers must efficiently deliver electric power to both battery options. For this purpose, this article proposes an advanced...

Interoperability of the Voltage/Current Doubler Converter Employing Bipolar Pads with the SAE J2954 VA WPT2/Z2 for EV Wireless Charging

This paper investigates the interoperability of the proposed voltage/current doubler (V/I-D) converter used for wireless charging of electric vehicles (EVs), which achieves high efficiency when charging both 400V and 800V batteries at the same power. Nominally, the V/I-D converter employs bipolar pads (BPP) at both the primary and the secondary...

Compensating parasitic motions and cross-couplings in compliant mechanisms: The development of a new compensation strategy to diminish unwanted motions

There is a constant drive to make the next generation machines in the semiconductor industry more precise and faster. For this machines with a high repeatability, good dynamics and long lifetime are needed. Compliant mechanisms are suitable candidates to be used in this kind of machines because they can be manufactured monolithically, don’t wear...

Dynamic Testing of GE Multilin 869 Motor Protection Relay for Stator Inter-turn Faults

Induction motors have a significant role in every aspect of modern living. They are extensively used in every industry because of their robust construction, easy operation, controllable and adaptable features. Therefore, occurrence of faults in these machines are a major concern. The protection schemes implemented in a network plays an important...

Model Predictive Control for Helicopter Flight Control: Evaluating Linear and Nonlinear Model Predictive Control for Reducing Cross-coupling Effects in Helicopter Flight

Model predictive control is an optimal, model-based control method that has the powerful capability of directly including input and output constraints. Next to this, it is known that helicopters are hard to fly with its complex, unstable and highly coupled dynamics. With the introduction of the concept of handling qualities, guidelines for...

Objective Evaluation of the Retention of Manual Control Skills Using a Cybernetic Approach

Pilots’ manual flying skills have notably reduced due to the increase in flight deck automation over the last decades. This has resulted in a growing concern that today pilots lack the skills to safely and successfully prevent or recover from unexpected aircraft upset events or to take over controls after a sudden transition to manual flying....

Modeling Key Pathways Proposed for the Formation and Evolution of “Cocktail”-Type Systems in Pd-Catalyzed Reactions Involving ArX Reagents

Reversible leaching of palladium nanoparticles occurs in a variety of catalytic reactions including cross-couplings, amination, the Heck reaction, etc. It is complemented by capturing of soluble palladium species on the surface of nanoparticles and de novo formation of nanoparticles from Pd precatalysts. We report here a detailed computational...

A Capacitively Degenerated 100-dB Linear 20-150 MS/s Dynamic Amplifier

This paper presents a new dynamic residue amplifier topology for pipelined analog-to-digital converters. With an input signal of 100 mV_pp,diff and 4 × gain, it achieves-100-dB total harmonic distortion, the lowest ever reported for a dynamic amplifier. Compared to the state of the art, it exhibits 25 dB better linearity with twice...

Computer aided EMC analysis: A review of available tools

A review is given of methods for the analysis of intrasystem electromagnetic compatibility. Emphasis is placed on pocket calculator programs and on the SEMCAP computer program. Taking into account the applications at NLR, we conclude that both tools can be very useful for such an analysis. As far as antenna-to-antenna coupling is considered, the...

Investigation of a cross-coupling drift compensation method on a single axis gyro stabilized platform

In this report the phenomenon of cross-coupling drift (both S-IA and S-OA) due to vehicular angular movements is investigated. In a hardware test set-up, using an experimental Single Axis Platform composed of surplus parts from the former Eldo-A program, the theoretical result as well as a proposed method of compensation is verified.
