Success! My first circuit board prototype of the IEC 61000-4-5 Combination Wave Generator (aka Lightning Surge Generator, aka Impulse Generator) is working after a month of development. This PCB has greatly improved safety and usability compared to the original perfboard. #electronics

Surge waveforms are compliant to IEC 61000-4-5's 1.2/50 μs & 8/20 μs requirements.
⚡ Open-Circuit Voltage:
- 1.02 kV, Front time: 1.33 μs, Duration: 53.60 μs
⚡ Short-Circuit Current:
- 484 A, Front time: 7.53 μs, Duration: 21.51 μs
