Consider a full wave diode rectifier with R-L load, given that Vs(t) = Vssinωt, where Vm = 170 V, f = 60 Hz and load R = 500 Ω. What is the value of series inductance to limit the ripple current to 5% of Idc (Design by ignoring harmonic order greater than three).
For the circuit shown, Vs = 230V (rms), 50 Hz, Ls = 5 mH and E = 110V. The peak instantaneous output current will be ______ Ampere. (upto 2 decimal places).
SCRs with a peak forward rating of 4 kV and an average on-state current rating of 100 A are used is a single-phase mid-point converter. If the safety factor is 2.5, then power that can be handled by this converter is_________ kW. (upto 2 decimal places).
For a given single phase full bridge converter, if each SCR has 1.5V of voltage drop while conducting, then the required PIV of each SCR is_______ volts. (upto 3 decimal places).
In the circuit shown, AC source is 120V rms at 60 Hz, L = 50 mH and Vdc = 72V. If the current in the circuit is given by the expression
i = 9.82 – 3.82ωt
