“…With the finite amount of switching times of the unidirectional switches, commutation has become a complex task where the controller has to provide a significant amount of processing time in contrast to conventional voltage source inverters. Therefore, to ensure that there will always be a path to the inductive load current to continue despite the switching state, various commutation algorithms have been developed for matrix converters [73][74][75][76][77][78][79][80][81][82][83]. Among them, four step commutation is widely used in implementations.…”

In recent years, economic and environmental considerations have led the industry towards energy efficient technologies. As a result, in the context of industrial motor drives, Brushless DC (BLDC) and Permanent Magnet Synchronous (PMS) motors have become popular as energy efficient and reliable alternatives for induction motors. Both BLDC and permanent magnet synchronous motors are electronically commutated based on the position of the rotor by using voltage source inverters that consist of a rectifier, a DC link capacitor and an inverter. In comparison to the other electronic components in the circuit, the DC link capacitor has a limited lifetime, which is severely dependent on the ambient operating temperature. However, with advancements in technology, direct power converters such as matrix converters that do not employ DC link capacitors are becoming popular in industry. At present, matrix converters and similar style direct converters are economically feasible in high power applications and are expected to be economically feasible for low power ratings in the future.

This paper describes the performance and loss analysis of a three-port AC/DC/AC three-phase power converter based on the Japanese 10-15 mode vehicle driving pattern. The structure of the proposed circuit consists primarily of an indirect matrix converter (IMC) and a boost converter connected to the neutral point of the induction motor. The first part of this paper discusses a method for the optimization of the boost converter during single pulse modulation. The authors propose the implementation of feedforward compensation in the boost converter to suppress the battery ripple. Results show that the battery ripple is reduced by approximately 72% during single pulse modulation. The second part of this paper illustrates the behavior of the proposed converter when simulated under the Japanese 10-15 mode driving pattern. Converter losses under different conditions and circumstances are studied, and on the basis of the results, the optimal point of the power control for the converter is discussed.

“…This utilization of converters for high frequency applications drains large current from the source with poor input power factor and harmonic distortions in input voltage and current. To avoid these issues of power quality [2], maintaining the power factor and reduction of harmonic generation is a major concern for these converting operations. For the improvement of input power factor many filtering methods have been employed in which a simple passive element (inductor) is the basic filtering option with also harmonic reduction for these converters.…”

Abstract:-In this paper we propose a high frequency unity power factor correction resonant converter for electronic ballast lamps. The change in the switching frequency of the converter changes the output voltage amplitude of the converter also changing the harmonic distortion in the output voltage and current. To maintain the input current shape the converter employs small energy tanks reducing the THD of the input current. The efficiency, THD of the converter are analyzed in MATLAB Simulink software with respect to change in switching frequency and presented in this paper.
