“…However, as switching frequencies increase, the sizes of EMI filters also increase significantly, which is highly detrimental to improving converter power density. Additionally, hardware-based strategies such as soft-switching techniques [18] and optimized circuit layouts [19] are used for EMI suppression. However, soft-switching techniques require additional components, hindering cost reduction and the increase in power density.…”

When utilizing high-dimensional chaotic signals for frequency modulation, achieving a uniformly distributed power spectrum is a challenging task. This paper addresses this challenge by proposing a power spectrum homogenization strategy based on distribution transformation. The strategy transforms the task of achieving a uniformly distributed power spectrum in frequency modulation of high-dimensional chaotic signals to solve and equalize the probability density function of the chaotic signals, thereby further enhancing the ability of high-dimensional chaotic signals to suppress electromagnetic interference. Firstly, the difficulty of obtaining a smooth probability density function of chaotic modulation signals is solved using the kernel density estimation algorithm. Then, a distribution transformation algorithm is proposed to convert non-uniformly distributed chaotic modulation signals into uniformly distributed chaotic modulation signals. By using uniformly distributed chaotic modulation signals for frequency modulation, the objective of power spectrum equalization is achieved. Finally, taking the Chua’s chaotic signal as an example, the effectiveness of the proposed strategy is verified using an experimental platform based on a digital signal processor-controlled active clamping flyback converter.

In the real world, the presence of noise is undeniable. Electric fields, magnetic fields, temperature changes, atomic structures, and so forth are contributing to the reality and the magnitude of noise. Data acquisition of physical quantities in nature is always needed, which subsequently is required for the interpretation in the laboratory. For this reason, the presence of noise needs to be eliminated or known. In the four-probe measurement system, the two electrodes are injecting current, while the other two electrodes are used for acquisition of the arising voltage. The voltage that arises is greatly influenced by the natural environment and the conductor cables, which are usually in long spans and unprotected. For this reason, noise minimization is very needed. This study aims to compare several types of conductors in reducing noise and reducing attenuation. The study was conducted in an open field with a 20-meter cable, and the front-end amplifier was varied to get the highest SNR.
