Overview


Essential details:810-014025-004 LAM PLCs/Machine Control

With the increasing power and decreasing volume of equipment in the fields of telecommunications and servers, the application space of power modules of these devices is becoming more and more compact, and high-power high-density power modules have become one of the development directions of DC-DC switching converters in the future. DC-DC switching converter usually adopts the Printed Circuit Board (PCB) module form, specifically, the magnetic core is installed in the magnetic core slot of the printed circuit board, and then the semiconductor conversion unit is connected to the printed circuit board to form a power module, in which the transformer and winding are composed of the conductive layer of the printed circuit board. In the existing power module, the conductive windings in different conductive layers of the printed circuit board are connected through holes, which occupies a large area of the printed circuit board, affects the wiring of different conductive layers and the distribution of conductive windings, and leads to the technical problem of low power density of the power module.
