Phase Controlled Rectifier feeding DC Motor

In this Simulink model a single-phase full bridge phase-controlled rectifier feeding a DC Machine with constant load torque.

In this Simulink model I have made a single-phase full bridge phase-controlled rectifier using SCRs. The SCRs are controlled through two pulse generator. The input supply is single-phase AC voltage of 230V rms with fundamental frequency of 50Hz. The armature of DC motor is getting input from the rectifier. I have used preset model 01 DC motor with specification 240V 5HP 1750 RPM Field:300V. For give field voltage I have connected seperate constant DC source of 300V. The DC motor is seperately excited. The load torque is constant, which is in my case I have taken 55 N-m. Scope is used for visualizing the parameters waveforms.
