Hi,
The attached is a FET based inrush limiter for a Boost PFC’s output capacitance.
Is it worth having an inrush resistor for the X2 caps aswell (as shown). For example, for a 250W, 240VAC Boost PFC, a 1R,3W inrush resistor could be used just upstream of the X2 caps.
Or is this not worth it?
The X2 capacitor datasheets don’t allure to inrush protection measures
