Matrix converter (MC) is an AC-AC power converter topology that directly converts energy from AC source to an AC load without using any energy storage components. Therefore, the disturbances in the input voltages can propagate onto the output side and degrade or even deteriorate the performance of motor load. This paper investigates the behavior of MC and its influence to the performance of ind...

Three-phase to single-phase matrix converter (TSMC) is used as the transmitter for transient electromagnetic method (TEM) instrument, instead of an AC-DC converter and an H-bridge inverter. The transmitter produces excitation current for primary field. The output current has a waveform with a bipolar square of half duty cycle, which is required by TEM. The space vector PWM based on input curren...

This paper develops a Takagi-Sugeno fuzzy approach for modeling a DC-DC voltage-mode controlled buck converter as a nonlinear, nonsmooth system to capture all the essential fast-scale nonlinearities that occur at controller clock frequency. A tractable mathematical stability analysis, employing nonsmooth Lyapunov functions, is proposed for identifying converter fast-scale instabilities and the ...

Matrix converter is a single-stage converter which directly connects a three-phase voltage source to a three-phase load without dc-link components. Therefore, any harmonic distortion and imbalance in input voltage directly reflect to the output of the converter. Recently, many researchers have made an effort to cope with this problem. In this paper, under distorted input voltage conditions, beh...

In this study an Adaptive Neuro Fuzzy Inference System is introduced to select the switching states of Matrix Converters. Matrix converters have received more attention in research and industrial application due its advantages like four quadrant operation, sinusoidal input and output waveforms, controllable displacement factor, less number of switches etc., Matrix Converters are efficient in sp...

The nonlinear behaviour of the buck converter controlled by double-edged PWM waveform is studied in this paper. The stability of the system is analyzed using the state transition matrix over one switching cycle (the monodromy matrix) including the state transition matrices during each switching (saltation matrices). Three supervising control methods are applied to extend the normal period one o...
