Description

Technical Field

[0001] The present invention relates to the technical field of track litz wire routing installation, and in particular to a track litz wire routing installation structure based on a contactless power supply system. Background Art

[0002] The WPS contactless power supply system (WPS) is a technology that transmits power and signals without mechanical contact, utilizing magnetic field coupling for electrical-magnetic-electrical energy conversion and transmission. The primary and secondary components of the WPS system are independent, with no mechanical or physical contact between them. The magnetic field is maintained by air, allowing for relative motion between the primary and secondary components. The alternating current in the primary coil of the system operates at a frequency of 20 kHz, 400 times higher than the typical industrial frequency. This allows for efficient power transmission across a large air gap between the primary and secondary components while ensuring safety. The WPS system's structure allows for the separation and relative motion of the primary and secondary components. The primary coil extends into a long conductor loop, capable of supplying energy to multiple secondary loads and possessing the basic operational capabilities required for semiconductor fabs. Because the system relies on high-frequency magnetic fields for energy transmission, special attention must be paid to the impact of high-frequency effects on system performance, particularly the resulting losses. To ensure efficient and reliable operation, it is necessary to thoroughly analyze the mechanisms by which high-frequency environments affect wireless power transmission systems. Therefore, it is necessary to consider the losses caused by the skin effect and proximity effect, two high-frequency effects.

[0003] Skin effect means that when high-frequency current flows in a conductor, it is mainly concentrated on the surface of the conductor, resulting in a decrease in the effective cross-sectional area of ​​the conductor, an increase in resistance, and thus an increase in conduction loss. Simulation shows that the skin effect is closely related to frequency. The higher the frequency, the more obvious the skin effect, the smaller the skin depth, the greater the equivalent resistance of the conductor, and the more serious the skin effect loss of the system. Figure 6 The figure shows the distribution of current density when a current of 1A / m2 flows through the conductor at different frequencies.

[0004] The proximity effect is when two or more conductors are close together, and the high-frequency current in each conductor generates eddy currents in the other conductors, resulting in uneven current distribution in the conductors. The higher the frequency and permeability, and the smaller the resistivity, the more pronounced this phenomenon is. This uneven current distribution increases the effective resistance of the conductors, thereby increasing losses. Figure 7 The figure shows the distribution of current density inside the conductor surface when the proximity effect occurs in two parallel straight wires. Figure 7As can be seen, the proximity effect causes the current density in the coil to lose symmetry, particularly when the currents in the two conductors flow in opposite directions, causing the current to concentrate on the inner side of the conductor. At a frequency of f = 10 kHz and with the currents flowing in opposite directions, the current density distribution in the two conductors shows significant unevenness. When current flows through adjacent conductors, an alternating magnetic field is generated, thus causing the proximity effect.

[0005] The proximity effect is more severe than the skin effect. While the skin effect restricts the conductive area of ​​a wire to a small portion of its surface, increasing copper losses, the proximity effect generates eddy currents caused by the alternating magnetic field of currents in adjacent winding layers. The magnitude of these eddy currents increases exponentially with the number of coil layers. [Multilayer coils and their proximity effect]

[0006] Therefore, we propose a track litz wire installation structure based on a contactless power supply system. In actual use, it is necessary to optimize the overall structural design to reduce the losses caused by high-frequency effects on the system. At the same time, a corresponding track litz wire wiring diagram is designed based on actual site requirements to meet actual on-site requirements and minimize losses caused by high-frequency magnetic fields while ensuring functionality.
