Improved continuously variable self and mutual inductor

A Compact Differential Inductor with Improved Self-Resonance Frequency

An original multi-layer structure is proposed for the realization of monolithic differential inductors. Compared with standard differential topologies of equal inductance, it can reduce the area occupation by more than 50% and increase the self-resonance frequency fSR up to 30%. However, because of the high resistivity of the lower metal layers, the quality factor Q decreases by 25−40% and make...

Design of Continuously Variable Transmission (CVT) with Metal Pushing Belt and Variable Pulleys

Nowadays, automakers have invested in new technologies in order to improve the efficiency of their products. Giant automakers have taken an important step toward achieving this objective by designing continuously variable transmission systems (CVT) to continuously adapt the power of the engine with the external load according to the optimum efficiency curve of e...

Design and Measurement of the nH Level Mutual Inductor

A nH level mutual inductor has been designed and used as the standard impedance for measuring the equivalent inductance of current shunts. A method has also proposed to measure the mutual inductance against the ac voltage standard and current standard at frequencies up to 200 kHz.

Modelling and Optimization of Toroidal Continuously Variable Transmission in ECE Driving Cycle

In the present study, the aim is to optimize full and half toroidal continuously variable transmission (CVT) in order to minimize the vehicle fuel consumption (FC) in ECE driving cycle. First, the model of both CVTs’ efficiency is presented. The control strategy of CVTs speed ratio based on minimizing the vehicle FC is introduced, and the algorithm of calculating the vehicle FC is shown. Afterw...
