AI Technical Summary
Existing lightning surge equipment cannot simultaneously test combined waves and current waves, requiring users to purchase two sets of equipment, which increases costs and is inconvenient.
A multi-waveform lightning surge generator with automatic waveform switching was designed. It achieves automatic switching of different waveforms by using components such as a high-voltage generator, rectifier diode, charging switch, current-limiting resistor, pulse capacitor and waveform switching switch, combined with a controller.
This technology enables the integration of multiple waveforms into a single device, reducing user procurement costs and increasing automation.
