For a crude (low power) solution you can put a resistor between your diode bridge and the main filter cap, this will give much closer to the RMS value than having no resistor and also increases diode conduction angle and reduces peak diode current. -Roman -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
