Multilevel Inverters

Induction motor drives are employed in many of the industrial applications. The drives output depends on the inverter. Multilevel inverters are generally used in the induction motor drives but the dual inverter fed induction motor drive found more advantageous than the multilevel inverters. The performance of the Induction motor drive with open end winding for various levels of output voltage is presented in this paper. The inverter configuration implemented produces three-level, fourlevel, five-level and six-level in the output voltage waveform. The voltage and current harmonic distortion decreases as the number of levels are increased. The performance of the motor drive with the proposed inverter topology was found effective for sixth level. The simulation analysis of Induction motor drive with dual inverter is carried out in MATLAB-Simulink environment

This paper presents the direct torque-controlled induction motor drives (DTCIMDs) based on a retrofit 44-pulse rectifier (44PR). A 22-phase polygon autotransformer (PA) is designed to supply the rectifiers. The above structure improves the power quality standards in the power grid and complies with the requirements of the IEEE-519 standard for different loads. Besides, a power factor close to one is obtained for a wide range of DTCIMD performance. The results show that the total harmonic distortion (THD) of the input current under variable loads for 44PR is less than 3%.

Induction motor drives are commonly used for applications with vast variations in mechanical load for torques under nominal values. HVAC loads are among these loads. The most ideal scheme for induction motor drive design should include drive loss reduction, or efficiency improvement, proportional to load torque such that optimal performance of drive is not affected. In this paper, using analytical methods, an accurate model is proposed for induction motor drive design. This model allows us to utilize real control and classical control theory for better performance of drive control system. The most damaging mechanical load for induction motor drive is impulse load or so-called periodic load. A scheme proposed for power loss control includes loss control for this type of load, meanwhile, robustness of drive system and stator frequency stability are retained. Main advantages for this scheme are applicability and implementation on various induction motor drives with various powers, without any specific requirements and the least possible computation for the processors.

<span lang="EN-US">Fault identification is as much important as prior knowledge to mitigate the faults that might occur in inverter driven induction motor drives. In this paper, seven-level multi level inverter was taken up for testing of mitigation using redundant cell and the results were compared with five-level inverter to exhibit the performance of mitigation policy. This paper presents analysis of inverter feeding an induction motor drive when switch open and short fault occurs. When the fault occurs, the redundant cell activates and thus the drive system operates. In this paper, the function for redundant cell was explained with the results of drive system simulated in Matlab/Simulink.</span>

Induction motor is the backbone of current industrial applications. Multiphase machines can handle high power application easily. With the use of five-phase induction motor, advantage of both multi-phase and induction motor can be achieved. This paper presents analysis of five-phase seven level-based Induction motor system fed by packed U-cell based inverter. Modelling of five-phase induction motor is done with the help of mathematical equations using d-q axis transformation. Inverter voltage output comes to be approximately sinusoidal with 18.07% Total Harmonic Distortion (THD). Induction motor with specified parameters is simulated under no-load condition and attains steady state conditions after transient state.

Sensorless induction motor drives are widely used in industry for their reliability and flexibility. It’s very important to improve the performance of speed estimation in some cases, especial at low speed of IM drives. The authors have proposed and developed a model reference adaptive system (MRAS) based on discrete time sliding mode algorithm(DTSM), which has high performance for sensorless induction motor drive in low speeds. The new algorithm obtains the identification flux using the classic MRAS, and the PI adaptive law in MRAS is replaced with the sliding mode observer which is acquired by the error function. This paper presents the theory, modelling, simulation and experimental results of the proposed DTSM-MRAS based sensorless direct torque control induction motor drives.

This article proposes the space vector based decoupled centric and non-centric PWM techniques for open-end winding induction motor drive. To make the proposed configuration, 2-coventional inverters are fed on either side of open-circuited stator winding of induction motor. Therefore three level output is achieved. To obtain the control pulses for inverters in the proposed configuration reference sinusoids are used. All the proposed PWM techniques use the equal switching frequency. To obtain the validation for the proposed work various theoretical and simulation analysis is carried out using v/f control and the corresponding output voltage is verified experimentally using 1HP asynchronous motor.
