Abstract

The invention discloses a power supply and electrical equipment. The power supply is composed of an LLC control circuit, an input rectification circuit, a switch circuit, and an LLC transformer. The LLC transformer includes an EQ type transformer and a leakage inductor arranged outside the EQ type transformer. The input rectification circuit rectifies inputted commercial power into a direct current. The LLC control circuit controls connection or disconnection of a switch module, so that the direct current outputted by the input rectification circuit is converted into a pulsating direct current that is then transmitted to the LLC transformer. The LLC transformer carries out voltage conversion on the inputted pulsating direct current inputted and then outputs the processed current to a load. According to the technical scheme, the power conversion efficiency is improved; and the power occupied space is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a power supply and electrical equipment using the power supply. Background technique [0002] Large-sized TV sets have relatively high power. In order to reduce the thickness of the TV set, the power supply, constant current control module, main control board, driver board, etc. of the TV set are usually made on the same PCB board. The traditional TV power supply adopts EF type transformer, which combines the leakage inductance and the transformer body together, resulting in a large power supply, a large area of ​​the PCB board, and low efficiency. Contents of the invention [0003] The main purpose of the present invention is to provide a power supply, aiming at improving the conversion efficiency of the power supply and reducing the occupied space of the power supply. [0004] In order to achieve the above object, the present invention proposes a power supply, in...
