Abstract
The utility model relates to a power supply adapter for a vehicle, which comprises a low-voltage direct current input interface matched with a vehicle power supply, a direct current output interface, a high frequency generating circuit and a casing, wherein the low-voltage direct current input interface is connected with the high frequency generating circuit through a filter circuit, the output end of the high frequency generating circuit is connected with the filter circuit and the output end of the filter circuit is connected with the direct current output interface. Thereby, the power supply adapter for the vehicle can obtain a desired direct current power supply of 150V to 350V or an alternating current power supply of 200V+/-20V using an existing 12V vehicle direct current power supply, and can be used for charging small switching power supplies, such as a mobile telephone, a portable computer, etc. The utility model has definite operation significance for vehicle service configuration.
Description
The utility model relates to a kind of adapter that is used for providing on the vehicle charger standard charging power supply, particularly a kind of vehicle adapted power supply adapter.
At present, on automobile, all do not dispose the standard charging power supply of common mobile phone charging usefulness, thus, use the passenger of reference power supply all to bring very big inconvenience to driver who on vehicle, spends all day and need.
The purpose of this utility model is that a kind of vehicle adapted power supply adapter that the required standard charging power supply of mobile phone charging can be provided onboard at any time is provided for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the vehicle adapted power supply adapter that the utility model is designed, comprise the low-voltage direct input interface, direct current output interface, high frequency generation circuit and the housing that are complementary with automobile power source, the low-voltage direct input interface links to each other with high frequency generation circuit by filter circuit, the output of high frequency generation circuit connects filter circuit, and the output of filter circuit connects the direct current output interface.In order further to provide AC power required for special passenger, also be connected with direct current one exchange conversion unit at the output of filter circuit, the output of direct current one exchange conversion unit is connected with the interchange output interface.For standard and the stability that improves out-put supply; high frequency generation circuit is made up of oscillatory driver, switching circuit, high frequency transformer and Voltage Feedback current protection unit; the output of oscillatory driver links to each other with high frequency transformer by switching circuit, and the output of high frequency transformer feeds back to the signal of telecommunication by Voltage Feedback power protection unit the input of oscillatory driver.In order to improve and to guarantee stable AC power output, direct current one exchange conversion unit comprises sinusoidal wave driver element and the bridge switching circuit output unit of taking place, and the sinusoidal wave driver element that takes place links to each other with the control end of bridge switching circuit.
Resulting thus vehicle adapted power supply adapter, only need utilize the existing 12V car direct current power supply that is provided with of vehicle to import power supply as it, can obtain required 150～350V DC power supply or 200V ± 20V AC power, for mobile phone, switchette power source charges such as laptop computer are used, make driver and passenger can both carry out phone charging onboard and chargedly call and use computer, it is to vehicle
Service configuration has certain realistic meaning.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model circuit theory diagrams;
Fig. 3 exchanges output embodiment circuit theory diagrams.
In conjunction with the accompanying drawings the utility model is further described below by embodiment.
