Abstract

For instance, the scalar control is a variable regulation of volt per hertz to sets the magnitude scaling of the motor, of course by linearization of two parameters that is voltage and frequency, which sets to a constant ratio for the only concept of scalar control. In contrast, this method has the disadvantages that cannot decrease or increase the speed range from lower voltage of low speed or upper limit voltage of high speed, due to a certain regions are experiencing issues in constant ratio precision because of switch loss. The resulting output signal is not only has a high harmonic which would lead to losses in the form of heat, but is also causes poor performance at low frequency. For investigation, we used simulation using Direct Torque Control or also called DTC. The application of DTC, becoming one of the motor drive method of induction motor, and would produce the efficient power consumption because of switching pattern based on vector voltage. For simulation result, we use the test techniques when unencumbered and when burdened by parameters of rise time value, settling time value, and set point value.

Abstract

In this study, the IEEE 519 Standard as a basis benchmarking for voltage (THDV) and current (THDI) in draft performance. Comparative Study based onthree-techniques of 2-Level Converter (2LC) by using a Star-Connection Induction Motor (Y-CIM) in ExtraLow Voltage (ELV) Configuration.For the detail explanation, a primary inverter as Direct-Inverterby PWMdirect (PWM) degreesand asecondary inverter as Inverse-Inverterby PWMinverse(PWM + PI) degrees. It tends a modified algorithm,for eachof SPWM in six rules, and FHIPWM in 5th harmonics Injectedin standard modulation as the purpose for the Open-Ends of Pre-Dual Inverter in Decoupled SPWM for twelve rules, and Decoupled FHIPWM in combination of 5th harmonics Injectedin combination of two-standard-modulation. Those techniques are the purpose of two-inverter combination, which namelythe Equal Direct-Inverse (EDI) algorithmproduct of prototyping in similarities. The observation is restricted in voltage scope between Simulation by using Power Simulator (PSIM)and Application by using Microcontroller ARM STM32F4 Discovery.
