NST PFC cap question

I just hooked up a pair of 100uF 100V non-polar electrolytic caps in series 
(closest to the needed 41uF I could get) to the primary of my 15kV, 30mA NST 
for phase correction. (I don’t fully understand the PFC idea, but it sounded 
good and I thought Id give it a try) After running for 10 seconds they were 
getting warm and after another 10 seconds they were significantly warmer. Im 
sure if I continued to run them they would overheat. What can I do to fix 
this? Can I put a resistor in series to cut down the caps current? The 
resistor shouldn’t effect the phase shift of the caps right? 100V was the 
highest rating in the non-polar caps at the local electronics shop, so 
putting caps in parallel isn’t an option. Any ideas or links to PFC info 
would be greatly appreciated. Thanks
