I of course would just find the nearest PFC20 power stage, and light the logic up with a linear voltage regulator, and crank the output voltage down to 60(float on 48 volts), and walk away. This concept works boost or buck 12 volt to 420 output. Kinda wide output ratios... The higher the voltage the more efficient. But the Guts to a $1500 charger is kind spendy and most don't have a half dozzen or so littering thier shop. Also this works to over 5Kw. I have parts in numbers and I need to do a App note on stuffing DC into a PFC charger.... -- Rich Rudman Manzanita Micro www.manzanitamicro.com 1-360-297-7383,Cell 1-360-620-6266
