The bridge rectifier uses four diodes connected as shown in Figure. When the input cycle is positive as in part (a), diodes D1 and D2 are forward-biased and conduct current in the direction shown. A voltage is developed across RL that looks like the positive half of the input cycle. During this time, diodes D3 and D4 are reverse-biased. (a) During the positive half-cycle of the input, D1 and D2 are forward-biased and conduct current. D3 and D4 are reverse-biased. (b) During the negative half-cycle of the input, D3 and D4 are forward-biased and conduct current. D1 and D2 are reverse-biased. When the input cycle […]
