Parasitic power storage capacitor

How to extract parasitic capacitance?

We propose two methods to extract these parasitic capacitances, i.e., lump-sum parasitic capacitance can be extracted by measuring the resonant frequency differences (shifting), while the turn-to-turn parasitic capacitance can be extracted by multivariable nonlinear regressiontechniquesappliedon theimpedancefrequencyresponses.

What is parasitic capacitance?

The parasitic capacitance between the turns of an inductor (e.g. Figure 1) or other wound component is often described as self-capacitance. However, in electromagnetics, the term self-capacitance more correctly refers to a different phenomenon: the capacitance of a conductive object without reference to another object.

What is the difference between helical and parasitic capacitance?

While the lump-sum capacitance as well as the turn-to-turn capacitance are created by the helical structure intrinsically (we call them the structural capacitance in this paper and they are measured from the copper wire inductor), the parasitic capacitance from conductive yarns will contribute additional capaci-tance to the structural capacitances.

Can parasitic capacitance be ignored?

At low frequencies parasitic capacitance can usually be ignored, but in high frequency circuits it can be a major problem. In amplifier circuits with extended frequency response, parasitic capacitance between the output and the input can act as a feedback path, causing the circuit to oscillate at high frequency.

What is parasitic capacitance in e-textile devices?

e-Textile devices, such as antennas, inductors, interconnects, and more, which are integral components of smart clothing applications. But the parasitic capacitance induced by their micro-structure has not been fully understood. This capacitance greatly affects device performance in high-frequency appli-cations.

Can a storage capacitor be charged to a DC power supply?

The storage capacitors can be charged to any voltage set by a DC power supply. The source of power comes from the driving force behind the varying capacitance and not from the DC power supply. The maximum output power for the circuit was 10 nW, and at that power, the efficiency was 50%.
