Consider the circuit

SCRs with peak forward rating of 1.5 KV and average on state current rating of 40 A is used in single phase mid-point converter. If the factor of safety is 2, then the power that can be handled by this converter is firing angle is 0° is.

Calculate the most economic size (radius in mm) of a single core cable working on 132 kV, 3–Φ phase, if dielectric stress of 10 kV/mm can be allowed.

An initially unchanged 1 mF capacitor has the current as shown below across it. Then the voltage at t = 5 msec.

If the initial across the capacitor shown in figure is 50 V and switch is closed at t = 0, then the time at which energy stored in capacitor drops to 25% of its initial value will be …………μsec.

The frequency response of standard lag compensator is shown below. The lag compensator coefficient of the compensator system if the system time constant is 3 sec, is ______.

A 3-phase full converter fed from 3-phase, 400 V, 50 Hz supply is connected to R = 6 Ω and E = 400 V and large inductance so that output current is ripple free. The power delivered to load for firing advanced angle of 45° is

A second order negative unity feedback control system has phase margin of 80°, then the system phase angle at gain crossover fequency is
