Help required for this SMPS Battery Charger

Hi! The attached file is a schematic of 50KHz SMPS power supply which uses 325 VDC (after rectification of Mains 240 V). The required current for charging Lead Acid battery is approx 20 Amperes. Please give comment if any modification in the circuit is required. (note: isolated 12V DC is used for control circuit)
Voltage regulation is not necessary.

Whay bother asking the same question again, when you're going to get the same answers?
