1. [Half-Wave Rectifier] Design a half-wave rectifier circuit, such as below, which can convert a sinusoidal voltage input, Vs = 5sin(2π100 ∙ time), to an almost constant voltage output.
(a) Assuming Von = 0.9 V and R = 100 Ω , calculate C which makes the ripple voltage (Vr) is smaller than 0.1 V. Estimate Vdc, Idc, θc, ∆T, Ipeak, Isurge and PIV of the designed half-wave rectifier.
(b) Based on the calculated C, in Pspice plot Vs and Vout versus time on the sample graph to find out the values of Vdc, Idc, Vr and PIV.
Compare the simulation results with the hand-calculated ones.
(c) In Pspice, plot ID versus time to find out the values of Ipeak and Isurge. Compare the simulation results with the hand-calculated ones.
2. [Full-Wave Bridge Rectifier] Design a full-wave bridge rectifier circuit, such as below, which can convert a sinusoidal voltage input, Vs = 5sin(2π100 ∙ time), to an almost constant voltage output.
(a) Assuming Von = 0.9 V and R = 100 Ω , calculate C which makes the ripple voltage (Vr) smaller than 0.1 V. Estimate Vdc, Idc, θc, ∆T, Ipeak, Isurge and PIV of the designed full-wave bridge rectifier.
(b) Based on the calculated C, in Pspice plot Vs (using “voltage differential marker” function) and Vout versus time on the sample graph to find out the values of Vdc, Idc, Vr and PIV. Compare the simulation results with the hand-calculated ones.
(c) In Pspice, plot ID2 and ID3 versus time on the same graph to find out the values of Ipeak and Isurge. Compare the simulation results with the hand-calculated ones.
