Application Cases

Today, automotive power supply systems produce complex outputs, and the operation of components such as high-current motors and solenoid valves, as well as changes in different operating modes and climatic conditions, can cause fluctuations in the supply voltage. Such voltage fluctuations may pose challenges to the normal operation of electronic modules, particularly safety-related electronic systems such as airbag control circuits and ABS control circuits. To address these issues, the International Organization for Standardization (ISO) has published ISO 16750, which outlines environmental conditions and testing standards for electrical and electronic equipment in road vehicles, detailing methods and requirements for DC voltage testing. This standard considers the real-world environmental conditions that road vehicle equipment may encounter during its lifecycle, providing comprehensive testing specifications for the safety evaluation of road vehicle electronic devices.

The ATA-4000 series high-voltage power amplifiers from Aigtek can amplify arbitrary waveform signals, meeting the requirements for various waveforms in automotive electronics testing.

Experiment Name: Road Vehicle Electronic Equipment Superimposed AC Voltage (Ripple Injection) Test

Experimental Principle: The superimposed AC voltage (ripple injection) test aims to verify the performance of road vehicle electronic modules across different DC voltage ranges, including their operational capabilities at minimum and maximum supply voltages. DC voltage testing for road vehicle electronic modules typically adheres to a series of national and international standards, such as ISO 16750-2.

Experimental Setup Image:

Experimental Procedure: A signal generator is used to produce an AC signal, which is then amplified by a high-voltage power amplifier. Simultaneously, the power amplifier is adjusted to generate a DC signal superimposed at both ends of the test specimen. Data is collected via an oscilloscope for subsequent analysis.

Role of the Power Amplifier: As the core component of the entire experiment, the power amplifier provides highly stable DC signals and low-distortion AC signals, meeting the requirements of the ISO 16750-2 testing standard.
