A full wave controlled rectifier (SCR full-bridge) shown in fig. 3 is operating in inversion mode (i.e. motor/generator problem). In the motor model R-12, Vac-96 V and the AC power supply is √2 (120) sin(377t) V. The power delivered to the ac system is 1000 W (generator mode). The maximum variation in the load current i, is 10 percent of the average load current. A) Determine the value of the delay angle a B) Estimate the value of the inductance L.
