Problems solved by technology

At present, lightning electromagnetic pulse environment simulators and transient electromagnetic pulse simulators have been built at home and abroad, but there is no research on the development of high-voltage pulse environment simulators, and the assessment and testing of electronic components used in high-voltage pulse electromagnetic environments cannot be carried out.

However, when the high-voltage pulse and large current are triggered, electromagnetic radiation with a field strength of about kV / m will be generated through the transmission line. Such a high field strength can easily cause interference or even damage to the surrounding sensitive devices and sensitive electronic units. Therefore, it is necessary Conduct battery adaptability assessment for electronic components working in high-voltage pulsed electromagnetic environment
