computer SMPS RECTIFIER section fault finding and explanation
Rectifier section converts main AC input into the DC supply. RL 204 four diodes in this section for converting AC into DC , which are called as bridge rectifier .through full wave rectification by brige rectifier, +330V and -330V are obtained from main AC 220V supply. negative supply obtained from the bridge is called the floating negative.
#FAULT FINDING IN COMPUTER SMPS
low DC voltage output
check any of diode opens (RL 204)
#FUSE BLOW UP
check one or two diodes may short
