“…Although this structure can drive xenon lamp, it needs more time to ionise xenon lamp and is hard to ignite the lamp again after lighting failure. The architecture in reference [26] utilises AC source to charge capacitor and exploits multi‐stage voltage‐doubling circuit to achieve high‐voltage generation, which can successfully drive xenon lamp. However, this structure has the drawbacks of including a large number of components and without arc‐sustaining ability.…”
