ATA-4000 Series High Voltage Power Amplifiers for Road Vehicle Automotive Electronics Testing

Nowadays, the output of the automobile power supply system is complex. The operation of high-current motors, solenoid valves and other components, as well as the different working modes of the car and changes in the climate environment may cause fluctuations in the power supply voltage. This voltage fluctuation may pose a challenge to the normal operation of electronic modules, especially safety-related electronic systems such as airbag control circuits , ABS control circuits, etc. In order to address the above issues, the International Standards Committee (ISO) has issued the environmental conditions and test standards for electrical and electronic equipment on road vehicles ISO16750, which specifies the methods and requirements for DC voltage testing in detail. This standard takes into account the real environment that road vehicle equipment may be subjected to during its service life and provides a complete test description for the safety inspection of road vehicle electronic equipment.

Antai Electronics' ATA-4000 series high-voltage power amplifier can amplify any waveform signal to meet various waveforms in automotive electronics testing.

Experiment name: Road vehicle electronic equipment superimposed AC voltage (ripple injection) experiment

Experimental principle: The superimposed AC voltage (ripple injection) experiment is designed to verify the performance of road vehicle electronic modules in different DC voltage ranges, including their ability to work at the minimum and maximum supply voltages. DC voltage tests on road vehicle electronic modules usually follow a series of national and international standards, such as ISO16750-2.

Experimental process: Use a signal generator to generate an AC signal, which is then amplified by a high-voltage power amplifier. At the same time, adjust the power amplifier to generate a DC signal that is superimposed on both ends of the test piece. Use an oscilloscope to collect data and then analyze it.

The performance of the power amplifier: It is the core part of the entire experiment. Its role in this experiment is to provide highly stable DC signals and low-distortion AC signals to meet the ISO16750-2 test standard.
