Embodiment Construction
[0015] Such as figure 1 As shown, in the embodiment of the present invention, an industrial computer can be used to install the main control of labview, carry the NI6024 data card, use the analog output AOUT1 (-10V---+10V) to amplify the voltage of the program-controlled reference power supply 0V-30V, and use WBV121S07_0 .2 The voltage sensor, with a response frequency of 40KHz, drives and amplifies the analog output signal, and is powered by a separate set of positive and negative 15V power supplies.
[0016] Use the analog output AOUT0 (-10V---+10V) to amplify the voltage of the program-controlled superimposed power supply -15V---+15V, and use -15V as the superimposed reference point. According to this circuit design, the output voltage range of the power supply is 0V-50V. Use WBV121S07_0.2 voltage sensor with a response frequency of 40KHz to drive and amplify the analog output signal, and use the output of the superimposed power supply as the power supply for the sensor; i...

Description
technical field [0001] The invention belongs to the technical field of automobile detection, and in particular relates to a high-speed power supply system used for automobile electrical test. Background technique [0002] During the driving process of the car, due to the different vehicle conditions, road conditions, and environments, it will encounter various voltage waveforms and interference pulses. Therefore, an automotive electrical appliance must undergo various voltage and pulse tests before being loaded into the road test. , Such as Audi, BMW, Daimler, Volkswagen, Porsche, etc. have given such standard documents as VW80000. However, there are many harsh voltage conditions and high-speed pulses that cannot be realized with ordinary power supplies. Contents of the invention [0003] The purpose of the present invention is to provide a programmable control power supply system for high-speed power supply superimposition for automobile electric appliance test.
