Gents,
Have any of you run a PFC boost circuit from a 50 or 60Hz AC line with a
loop resistance on the order of 100 ohms?
We are currently looking for the most efficient method of delivering
1Kwatt through a lossy cable.
Method one is the simple step down transformer followed by a rectifier
bridge. The concern here is the poor PF of the rectifier bridge had
large capacitor bank.
The other option being considered is a PFC after the transformer. This
should bring the PF closer to unity but the concern is of there will be
a stability issue with the resistive input power.
Anyone have experience or care to speculate about the doability of a PFC
running from a resistive source in the 100 ohm range?
