A new capacitively coupled contactless conductivity detection (C(4)D) sensor with an improved simulated inductor is developed in this work. The improved simulated inductor is designed on the basis of the Riordan-type floating simulated inductor. With the improved simulated inductor, the negative influence of the coupling capacitances is overcome and the conductivity measurement is implemented b...

This paper describes the operation, design, implementation and performance of RF coupled resonator filters. It starts by considering discrete parallel inductor/capacitor resonators and then moves on to discuss the implementation of this style of filter at higher frequencies using short circuit co-axial resonators in place of the inductors. Introduction Shunt mounted resonators, comprising a dis...

Other than by reducing power, extending battery life in portable microelectronics amounts to increasing power efficiency, which when coupled with accuracy, translates to increasing filter inductance. The problem with higher inductances is magnetic cores require more space to prevent the onset of saturation, so accuracy and efficiency (via their need for bulky inductors) hamper the miniaturizati...

This paper proposes a high step-up DC–DC converter which integrates switched-inductor and switched-capacitor techniques with four-winding coupled-inductor. With technique, two primary windings of the coupled-inductor are charged in parallel discharged series to obtain voltage gain. Moreover, by adding sets diode-capacitor circuits on both side windings, not only can recycle energy causing spike...

A closed-loop high-gain switched-coupled-inductor switched-capacitor (SCISC) converter is proposed by combining a sawtooth wave generator, pulse-widthmodulation based (PWM based) compensator and nonoverlapping circuit for step-up DC-DC conversion and regulation. The power part between source VS and output VO contains two sub-circuits: (i) a switched-coupled-inductor (SCI) booster circuit, and (...

We propose two van der Pol oscillators with high-order nonlinearities coupled with an inductor and investigate various types of multimode oscillations. We confirm that these oscillations are stably excited by numerical calculations. In particular, we show the multimode oscillations in the thirteenth and fifteenth-power oscillator systems (the coupled oscillators with thirteenth and fifteenthpow...

A set of four coupled inductors is applied to a four-phase interleaved 1 kW bi-directional 14 V to 42 V dc/dc converter for automotive applications. The coupled-inductor structure is optimized, and the performance is examined through simulations and experimental measurements. Although coupled inductors offer bigger advantages in applications that require fast transient response, they also have ...
