I am making a variable power supply, but i have encountered a problem that i m getting 48 V DC after rectification of 36V AC. As i need 10 amp current and i read from some where that 1000uf/amp capacitor is recommended so i have total capacitance of 7000uf, is this the capacitance that is causing this abnormal behaviour? I havnt any circuitry to discharge this capacitance, Plz help me guys..
 

no no this is not problem.
capacitor is hold's Vp of sine wave that's why it shows 48v.
when you will connect your load with 48v . these voltages will demp.
so dont worry about it.
