Latest Patents

Cai's latest patents include advancements in transformer and power module technology. One of his notable inventions is a transformer module that features a magnetic core, a first winding, and a second winding. The magnetic core is designed with at least one magnetic column, which is partially covered by a multi-layer carrier consisting of horizontal copper foils and connecting copper foils. The horizontal copper foils are strategically placed on horizontal wiring layers, while the connecting copper foils serve to connect these layers. The first and second windings are configured to surround the magnetic column, with the second winding positioned outside the first. Both windings utilize a combination of horizontal copper foil and connecting copper foil, ensuring efficient electrical connectivity through surface-mounted pins.

Another significant patent involves a power module that incorporates a magnetic core, a first wiring layer, a first insulating layer, and a second wiring layer. This design allows for a first metal winding to be formed in the first wiring layer, with part of it wound around the magnetic core in a foil structure. The first insulating layer is partially covered by the first metal winding, while the second metal winding is formed in the second wiring layer and also wound around the magnetic core. This innovative approach enhances the performance and reliability of power modules.
