1) For a three phase full wave controlled rectifier with resistive (R) load, if the input supply voltage is (Vms-380 V , f= 50 Hz) and the firing angle (a = 120°), then do the followings:- a. Draw to scale the load voltage waveform. b. Determine the mean value of the load voltage. 2) For a single phase (ac to ac) voltage controller, if the input supply voltage is (250Sin314t) with frequency (50 Hz) and the load is (R=5 2). Draw the controller circuit, and then do the followings: - a. Determine the rms value of the output voltage at firing angle (a=60 ). b. Determine the value of (a) in order to obtain output voltage of (70.7 V).
