Abstract

A modern control of electric motor’s speed in an industry needs a variable direct voltage. Mostly, the variable of the DC motor speeds needs to be control simply by adjusting the voltage variable at the terminal. In industries, the usage of DC power is limited. Therefore, the support of rectifier in the DC motors is needed to change AC voltage to DC voltage. Moreover, industries need a concrete rectifier to increase performance of its DC shunt motor. The variable direct voltage can be supplied by semiconductor devices such as SCR. The output voltage of a SCR rectifier depends on the delay angle of the SCR. The aim of this research is to make a SCR rectifier circuit and applying it for observing the characteristics of a shunt direct current motor. The result shows the circuit can work to demonstrate the shunt motor characteristic. The support of proper rectifier will be maximizing the performance of DC shunt motor. So that, supported the productivity in each industry. This rectifier uses a power transformer which acts as a three-phase line voltage ballast. This is because a rectifier circuit that uses a thyristor (SCR) cannot withstand relatively high unstable voltages. If the voltage becomes unstable, it may not be possible to properly control the start time of the thyristor. The ignition angle of the rectifier circuit is regulated by a control circuit which acts as a pulse angle transmitter (α) in the rectifier power circuit. The testing on this research is using PSIM software to test the performance of rectifier design before it applied in a prototype. The testing result show relationship between velocity ꞷm and armature current Ia, the relationship between torque (T) and armature current (Ia). The result of this research show that the greater the delay angle of the rectifier, the lower the output voltage of the rectifier which is equal to the motor input voltage. When the input voltage to the motor decreases, the motor speed m decreases. The effectiveness of the usage thyristor component in this experiment is supporting the performance of rectifier. The processor that use in this rectifier, as a form of launch at the gate, uses the TCA 785 chip, which acts as a gate signal generator for the thyristor, to operate the thyristor and generate a DC waveform at the output terminal. Therefore, customize design in this research can be used to test the characteristics of a shunt winding DC motor.
