In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...

The input electrical impedance behaves as a capacitive when a piezoelectric transducer is excited near its resonance frequency. In order to increase the energy transmission efficiency, a series or parallel inductor should be used to compensate the capacitive impedance of the piezoelectric transducer. In this paper, the effect of the series matching inductor on the electromechanical characterist...

In this paper, a novel lossless floating inductor simulator with four resistors, a grounded capacitor and five two-terminal active components such as negative impedance converter, current follower and voltage follower, is presented. The capacitor in the floating inductor simulator is grounded, which provides suitability for integrated circuit fabrication. However, it needs resistive matching co...

An eddy current sensor with an ink-jet printed flexible inductor has been designed and fabricated. The inductor has been designed by means of software developed in-house. It has been fabricated by ink-jet printing with silver ink on a flexible substrate. The inductor is a part of the oscillator circuit whose oscillating frequency is measured by a microcontroller. The sensor characteristics have...

Inductor with gradual changed metal width and space by good design can get better Q factor than the inductor with fixed metal width and space. In this paper, a simple wide-band inductor model is presented considering both the increase of resistance and the decrease of inductance due to the skin and proximity effects. This model has been verified with simulation and the experimental results of s...

This paper presents the electrical and thermal analysis of an OLED module. The OLED module consists of the OLED element and the DC-DC converter incorporated in its backplane. The DC-DC converter is realized as an integrated circuit and uses an external inductor. The inductor is embedded in the substrate of the backplane and has a spiral geometry. The DC-DC converter is highly efficient, but a f...

The discontinuous conduction mode (DCM) of the inductor current is an effective way to achieve high efficiency and power density inverters because it has advantages zero-current switching small inductance filter inductor. Although DCM can operate at a fixed frequency, there been no linear model for realizing high-performance digital control. This paper provides solution this problem. Firstly, f...
