What is the function of diodes D1D2 during the positive half cycle in a bridge full wave rectifier?
What is the function of diodes D1D2 during the positive half cycle in a bridge full wave rectifier?
During the positive half cycle, diodes D1D2 are forward biased and act like closed switches, conducting the current.
What is the function of diodes D3D4 during the positive half cycle in a bridge full wave rectifier?
What is the function of diodes D3D4 during the positive half cycle in a bridge full wave rectifier?
During the positive half cycle, diodes D3D4 are reverse biased and act like open switches, not conducting the current.
What happens during the negative half cycle in a bridge full wave rectifier?
What happens during the negative half cycle in a bridge full wave rectifier?
During the negative half cycle, point B becomes positive with respect to point A, causing diodes D3D4 to conduct while diodes D1D2 do not conduct.
