I have a small circuit that draws 30ma @ 160-170V. I'm currently using a rectifier off mains and a filter cap as an unregulated power supply. I measured the power factor at 0.6..... I've read that there are some tricks to get the PF closer to 1 with just some passive components, but have not read any design notes on how specifically to accomplish this.
Is it as simple as installing an inductor in line between the rectifier and filter cap?
