Abstract

The invention relates to a printed circuit board-based power converter, which comprises a shell and a printed circuit board, wherein the printed circuit board is fixed in the shell; the printed circuit board is provided with a power connecting base, at least one power interface and at least one USB interface; the power connecting base is connected with an external power supply through a power line; power conversion circuits are distributed on the printed circuit board; each power interface is connected with the power conversion circuits; and each power conversion circuit comprises an overload protection circuit, an over-temperature protection circuit and a USB charging circuit. According to the printed circuit board-based power converter, a plurality of circuits are integrated on the printed circuit board, so that the integration level is high, the scheme is flexible and the process is simple. In addition, a direct-current low voltage power supply electronic product can also be charged through the USB interface besides that a household appliance is supplied with a voltage by a normal power interface. The printed circuit board-based power converter is reliable in quality, small in size and intelligent, environment-friendly, efficient and energy-saving in use.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power converter based on a printed circuit board. Background technique [0002] With the improvement of the quality of life, the application of electronic products is becoming more and more extensive, people's demand for charging electronic products is getting higher and higher, and corresponding requirements are put forward for power converters. The power converter using the USB charging interface is an effective way to improve the charging of electronic products. Although ordinary household power converters provide interfaces for household appliances, due to the single interface of household appliances and no USB charging interface, household appliances and electronic products cannot be charged at the same time, which is not flexible enough, and the user experience is also poor. Moreover, with the increase of human production activities, the weather changes faster and...
