1. The problem statement, all variables and given/known data What is the name given to this type of circuit? Sketch output voltage waveform for a sine wave input across nodes A-B. 2. Relevant equations Please see attachment for circuit. 3. The attempt at a solution Well im inclined to say it is a full wave rectifier with a smoothing capacitor. I just cannot see how the current will move through the circuit. As v_in goes positive, D1 and D2 conduct. D3 and D4 will not conduct. I assume the current will split and so we will have current entering the capacitor through both terminals?? It seems as if once the current has gone in there is no way for it to come out? I really dont understand this diagram! (unless I dont' understand AC properly..) Thanks.
