In a voltage multiplier circuit, each capacitor stage needs time to charge up to its target voltage. When you have a multiplier with multiple stages (e.g., 4x or more), the input current gets effectively divided across these stages. This means the charging process is spread out, and each capacitor charges more slowly as a result.
While GPT's interpretation is partially correct, there’s a key point to understand: As you increase the number of stages, it will indeed take longer for the entire multiplier circuit to reach higher voltage levels. You can still discharge this stored energy at nearly the same current as your input, but it will be delivered as a pulse (a brief surge of current, also known as a Joule pulse).
The main downside here is a trade-off in output frequency. The output frequency becomes lower than the driving frequency due to the longer charging times and inherent losses (from diodes and other components). These losses introduce a significant efficiency drop, meaning the input power isn’t fully converted to useful output power, resulting in a noticeable input-output discrepancy.
