Power supply problems
(OP)
Im currently in the design process of a 240vac to 0-24vdc adjustable power supply with 0-3.3amps adjustable current
i have a 240vac to 24vac transformer wired in series with output of 26.8-27.0vac that feeds a single full wave bridge rectifier that outputs 24.4vdc this is where the problem comes. i need it regulated but with vf of bridge rectifier being 2.4-2.6v and the average voltage drop out of 3-5amp regulators being 1.2 - 1.4 volts is the only option buying a 30vac transformer or is there another way around this? as i need top voltage of 24vdc

You'd probably follow it with additional circuitry to provide the variable voltage and current you want.
These functions could all be integrated into one design if you're ambitious.
Or you could just order an off-the-shelf adjustable PS if you're not...

is there anyway i can cross over between parallel and series wiring on transformer to utilize some part of the transformer not being used already? as i understand each side has 6 pins and all i use is 4? if not what are these misc. pins for?
