Abstract

The invention discloses a power conversion method and device. The invention relates to the field of electronic technology, and in particular, to a power conversion method and device. The method includes: detecting a converted input voltage input to the power conversion device as a first input voltage; based on the corresponding relationship between the input voltage and the output power, determine that the converted output power of the power conversion device is the first output power corresponding to the first input voltage; based on the first input voltage, output the first output power One output power solves the technical problem in the prior art that the power adapter can only support one kind of power source with a specific output power for charging, and realizes the technical effect that the power adapter can support a variety of power sources with different output powers for charging.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a power conversion method and device. Background technique [0002] With the advancement and development of science and technology, electronic devices are increasingly used in people's lives, such as: people can use mobile phones to make calls, use game consoles to play games, and people can carry light and portable laptops with them. For work and leisure, because in real life, electronic devices often cannot directly use household electricity, because the power supply voltage used at home is 220 volts, and the power supply voltage required by common electronic products is generally 5 volts to About 20 volts, so the electronic equipment in our life is inseparable from the corresponding power adapter. The function of the power adapter is to convert the high voltage at home into a stable low voltage that can work, so that they can work normally. Without it, it will br...
