The full wave rectifier function is to produce a voltage or current that is purely DC or has some specified DC component. The output of the full wave rectifier has inherently less ripple than the half wave rectifier. The bridge rectifier circuit has an AC source with Vm = 415V at 60 Hz and a series RL load with R= 20 92 and L = 15 mH. a) Sketch the bridge rectifier circuit with RL load (2 marks) 4/5 b) Determine the average current in the load (4 marks) c) Estimate the load current based on the first 2 AC term in the Fourier series, n = 2 and n = 4. (8 marks) d) What is the power absorbed by the load and the power factor of the circuit (7 marks) e) Determine the average and rms current in the diodes (4 marks) The full wave rectifier function is to produce a voltage or current that is purely DC or has some specified DC component.
