    I have a toroidal transformer, primary 115vac, secondary 100vac 5amp series, 50vac parallel 10 amps.

    I am needing a 48 vdc for powering up a inverter. I just need something quick since I expect this to be discontinued shortly. Current requirements are less then 2 amps. I have these parts listed on the diagram.

    I can change out the filter caps to 10k.

    Any suggestions or comments would be great.

    Thanks Jim

    If the inverter is designed for battery input then it can take DC voltages up to 60-64 VDC. Your 50VAC connection should be fine after running through a bridge rectifier and ripple will be taken care of by the caps.(besure they are rated for the voltage, or they will blow) If the inverter draws much more than 2 amps then expect the ripple to become excessive without mucho filter capacitance, otherwise it will be fine for testing purposes.
