Description
Technical field
The utility model relates to a kind of Switching Power Supply, particularly relates to a kind of film xenon lamp Switching Power Supply.
Background technology
In the prior art, generally use linear power supply, linear power supply Primary Component is Correctional tube, linear power supply has two serious shortcomings, and one is that Correctional tube is operated in Linear Amplifer state, and loss is very large, thus make whole power-efficient very low, two is needs Industrial Frequency Transformers, such that power volume is large, quality weight, especially for the use on film xenon lamp.
Utility model content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of film xenon lamp Switching Power Supply.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts: this film xenon lamp Switching Power Supply comprises rectifier filter, DC converter, high frequency filter, drive circuit and controller, the front end of rectifier filter connects interchange input, the output of rectifier filter connects DC converter, the output of DC converter connects high frequency filter, the output of high frequency filter connects drive circuit and controller, the output of described controller connects drive circuit, and the output of drive circuit connects DC converter.
The beneficial effects of the utility model are: the structure of this film xenon lamp Switching Power Supply is simple, make loss of power reduction, efficiency raising, and the volume of filter also reduces David, thus reduces the volume of whole power supply, alleviates its weight.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, figure comprises rectifier filter, DC converter, high frequency filter, drive circuit and controller, the front end of rectifier filter connects interchange input, the output of rectifier filter connects DC converter, the output of DC converter connects high frequency filter, the output of high frequency filter connects drive circuit and controller, and the output of described controller connects drive circuit, and the output of drive circuit connects DC converter.
First AC power directly obtains direct voltage after the filtering of primary rectifier filter circuit, then becomes high-frequency ac square wave pulse voltage by inverter.Inverter output is isolated through high frequency transformer and changes suitable alternating voltage into, then becomes required VD through high-frequency rectification and filtering, and when AC-input voltage, load etc. change, VD also can change.The width of the square wave pulse voltage regulating inverter to export, makes VD keep stable.
The structure of this film xenon lamp Switching Power Supply is simple, makes loss of power reduction, efficiency raising, and the volume of filter also reduces David, thus reduces the volume of whole power supply, alleviates its weight.
