I need a power supply for pulsed RF amplifier.
Input 220V AC.
PFC is needed.
Mean output power is 150W.
Instantaneous load is 2.5kW.
Load duty cycle is 6%.
Load frequency is 1Khz.
Thank you for your interest in using Power Integrations' part.
Even though your mean power is not that high, your peak power is quite high. You need more than 1kW rated power supply to handle your peak power requirement. Unfortunately, we don't have yet solution for your needs. Sorry for that. Some RF amplifier I'm seeing which is maybe more cost effective solution is just using linear power supply so it can handle the peak power requirement. It is just bulky and not that efficient compared to switching mode.
