Full-Wave Bridge Rectifier• Current flows from the transformer, through CR4 to theground• The ground is attached to one end of R L , so currentflows up through R L• From the top of R L , current flows through CR3 back tothe transformer1:1+ +CR1200 VAC60 Hz282 VPEAKCR4CR3+CR2– – –RL+282V0V– 282VACINPUT+282V0VOUTPUTVOLTAGEAQR30020010-9307-1380
