Abstract

The invention provides a vehicle-borne power supply device. A vehicle-borne battery is connected in an exposed manner to receive a DC input power supply provided by the vehicle-borne battery, and simultaneously induces a plurality of groups of high-frequency voltages through a single separate transformer, so as to convert the high-frequency voltage to an output voltage which outputs at least an AC and a DC voltage. Besides, the vehicle-borne power supply device further comprises a rechargeable battery which can be charged when the DC input power supply conducts input; and provides a spare power supply for the separate transformer when the DC input power supply stop inputting, so as to maintain the supply of the AC input voltage and the DC input voltage. The vehicle-borne power supply device provided by the invention has the advantages of multiple purposes, safety and continuity.

Description

technical field [0001] The invention relates to a power supply device, in particular to a vehicle-mounted power supply device. Background technique [0002] In recent years, due to the rapid development of the technology industry, various fields have been integrated with the application of electronic technology to further enhance the value and advantages of competition. As far as the automotive industry is concerned, the application and integrated design of automotive electronics is also increasing year by year, such as: LED-related product applications, multimedia audio-visual products, monitoring devices, and global positioning systems (GPS) and other products that are used in vehicles. have received considerable response. Of course, there are also many technologies that are improved designs to allow the vehicle to support more electronic products. Therefore, in any case, these business opportunities have clearly made automotive electronics one of the key development pro...
