Performance Analysis of T-type Inverter Based on Improved Hysteresis Current Controller

In this study, analysis and simulation of the electrical and mathematical model of a 3-phase and 3-switch delta inverter that fed a three-phase RL load were performed. First, the Matlab/Simulink model of the inverter was created. In this model, an RL load of R=10Ω and L=0.005 H was fed and various simulations were made. The simulation results were obtained using 3 step switching technique for different conduction modes. The delta inverter that has a simpler structure and less switching elements than conventional inverter structures can be easily realized with low-cost microcontrollers.

“…Thus, the feedback control system was tested according to the switching control signals for the operating frequency values (at kHz levels) according to different hysteresis bands. Compared with the traditional SPWM technique applied of the multi-level T type inverters, it can be said that the Total Harmonic Distortion (THD) of this type of controller usage is lower than the SPWM controlled inverters [6].…”

The inverters are frequently used in power electronics applications in the industrial area. Research on multi-level inverter circuit designs in power systems interfaces has intensified in recent years. The design type and quality of the inverter circuit topology is very important for the output voltage to be closer to the sinusoidal waveform. In addition, artificial intelligence techniques for the control algorithms of the power switches of the inverter circuit provide useful information in terms of monitoring the estimated the voltage conditions of the inverter output parameters. In this work, an Adaptive-Network Based Fuzzy Inference Systems (ANFIS) model is proposed to estimate the Total Harmonic Distortion (THD) value of the output current of a three-phase three-level inverter circuit. By changing the switching frequency in the control circuit of the inverter, a data set for the THD values of the inverter current is obtained by Fast Fourier Transform (FFT) analysis in MATLAB. This data set is used in a training and testing phase of ANFIS artificial intelligence algorithm, and the THD value of the current is estimated. At the end of the estimation, the mean absolute error (MAE) values for training and testing are obtained as 0.1894% and 0.4009%, respectively, thereby, an ANFIS estimation example for parametric data set analysis in a power electronics circuit run with Matlab-Simulink software, and a parametric simulation study is presented to the literature for power electronics circuit designers.

“…The rectifiers are usually influenced by the external disturbance and changing operation conditions. Various control approaches have been conducted for Viennatype rectifiers such as HCC method [9,10], carrier baseddiscontinuous pulse width modulation (PWM) [11], a lagging reactive power compensation method [12] and a model predictive control (MPC) [13][14][15]. In these control algorithms, classical PI controller has been employed to regulate the DClink voltage.…”

The Vienna-type rectifier is broadly employed in various implementations thanks to realizable three-level operation, simple structure and controllable DC-link voltage. This paper proposes an adaptive proportional integral (PI) with anti-windup based direct power control (DPC) to improve dynamic response during load change, DC-link voltage step change and start up and to reduce current tracking errors. An adaptive PI with anti-windup DC-link voltage control is utilized to enhance dynamic response of the DC-link voltage and the instantaneous power because the PI regulator affected by the load change and system parameter variations. The PI based conventional power control is used to indicate the availability and accuracy of the proposed control strategy. The proposed control strategy performs outstanding performance and copes with vigorous disturbances in contrast to the conventional strategy. A detailed theoretical analysis of the proposed approach has been performed. Extensive case studies carried out by PSIM software are performed to validate the excellent behavior of the proposed control strategy.
