Power supply framework integrating AC/DC and wide-input DC/DC designs

Abstract

The invention discloses a power supply framework integrating AC / DC and wide-input DC / DC designs. The framework includes a power module and external elements. The power module includes an aluminum substrate which has a size of a whole brick and a control panel. Power devices which are heating in a circuit are welded on the aluminum substrate. Control devices are installed on the control panel. The control panel and the aluminum substrate are connected into an up-down structure through a pin structure and can also be connected into a plane structure through a wire. The external elements include a rectifying bridge, an input PFC inductor and a PFC output capacitor. The inductor is capable of being installed on the aluminum substrate according to difference of conditions. When a power supply is of wide voltage DC input, the PFC inductor can be saved. The power supply frame work integrating all heating power devices onto the aluminum substrate so that heat radiation is convenient and a power supply circuit is simplified sufficiently and different power supplies can be designed through addition of simple external elements so that labor cost is reduced and the framework is capable of significantly shortening a research and development cycle.

Description

【Technical field】 [0001] The invention relates to a design framework of a switching power supply, specifically a power supply framework with simple heat dissipation treatment, convenient power size design and conversion, and integrated AC and DC input design. 【Background technique】 [0002] With the diversification of industrial power supply and communication power supply applications, in order to meet the different power supplies required by each customer, the previous design had to complete the whole process from control circuit to main power design. This approach often designs similar things repeatedly, but cannot be managed uniformly because of differences. In order to meet customer needs, many engineers who are proficient in all power supply designs are often needed. However, engineers who are proficient in main power design are scarce, resulting in many design problems, which not only delay the development progress, affect the delivery of prototypes, but also waste a ...
