Match the switch arrangements on the top row to the steady-state V-I characteristics on the lower row. The steady state operating points are shown by large black dots.
In the 3-phase inverter circuit shown, the load is balanced and the gating scheme is 180∘ conduction mode. All the switching devices are ideal.The rms value of load phase voltage is
In the circuit shown, an ideal switch S is operated at 100kHz with a duty ratio of 50%. Given that∇ ic is 1.6A peak-to-peak and I0 is 5A dc, the peak current in S is
A half-controlled single-phase bridge rectifier is supplying an R-L load. It is operated at a firing angle a and the load current is continuous. The fraction of cycle that the freewheeling diode conducts is
Thyristor T in the figure below is initially off and is triggered with a single pulse of width 10 ms. It is given that L = (100/π)μH and C = (100/π)μF. Assuming latching and holding currents of the thyristor are both zero and the initial charge on C is zero, T conducts for
