A bridge converter is fed from a source Vs = Vm sinωt as shown in the following figure. What will be the output voltage for a firing angle of α? Assume continuous conduction.
A single phase half wave rectifier circuit is shown in the figure. The thyristor is fired at 30° in each positive half cycle. The values of average load voltage and the rms load voltage will respectively be
A single-phase two pulse diode rectifier has input supply of 230 V, 50 Hz and load resistance R = 30 Ω. The value of inductance to be connected in series with ‘R’ so as to limit the current ripple factor 6% is (Assume second harmonic component as the most domination component of Ir (ripple current) and neglect higher order even harmonics).
A single-phase half-controlled bridge rectifier is feeding a load drawing a constant and ripple free load current at a firing angle α = π/6. The harmonic factor (HF) of input current and the input power factor respectively are
A 3-phase fully controlled bridge converter with freewheeling diode is fed from 400 V, 50 Hz AC source and is operating at a firing angle of 60°. The load current is assumed constant at 10 A due to high load inductance. The input displacement factor (IDF) and the input power factor (IPF) of the converter will be
