The rectifier is fed by a 460 V AC 60 Hz voltage source. The armature voltage is provided by a three-phase rectifier controlled by two PI regulators. The 200 HP DC motor is separately excited with a constant 310 V DC field voltage source. When α 60 for some duration of time no device conducts so called discontinuous mode of operation. It models a two-quadrant three-phase rectifier drive for a 200 HP DC motor. MATHEMATICAL MODEL OF 3-PHASE RECTIFIER Current simulations include a 3-phase rectifier with a half-mix, as well as a full-wave rectifier 21-24. Depending on value of firing angle, circuit can operate in two different modes. Simulation model of 3-phase PWM rectifier by using MATLAB/Simulink (Salam Waley Shneen) 3737 2. Diodes are connected in parallel with RC snubbers (1000 ohms-0.1 uF) The measurement output of Diode2 and Diode3 is used to observe the diode voltage and current. The rectified current is filtered by a 200mH inductance. With purely resistive load current will be in phase with load voltage. A 10 ohm load is fed in DC through a three-phase rectifier from an inductive source (5 mH 120 V rms). So, line voltage are necessary to draw Phase shift between two line voltages is 60 degree & between two phase voltages it is 120 degree Each phase & line voltage is sine wave with the frequency of 50 Hz. Project Specs: To design controlled full-wave three-phase rectifier with RL-load. This project were done as a part of ROBT 307 Power Electronics course in Nazarbayev University. In the circuit shown above when any device conducts, line voltage is applied across load.
