Novel Modulation Method for Multidirectional Matrix Converter
This study presents a new modulation method for multidirectional matrix converter (MDMC), based on the direct duty ratio pulse width modulation (DDPWM). In this study, a new structure of MDMC has been proposed to control the power flow direction through the stand-alone battery based system and hybrid vehicle. The modulation method acts based on the average voltage over one switching period conc...
متن کاملModulation and Control Techniques of Matrix Converter
The Matrix converter is a forced commutated Cyclo-converter with an array of controlled semi conductor switches that connects directly the three phase source to the three phase load. The matrix converter is a direct AC-AC Converter. It has no limit on output frequency due to the fact that it uses semiconductor switches with controlled turn-off capability. The simultaneous commutation of control...
متن کاملA Novel Frequency Changing Device: Matrix Converter
The field of soft conversion from one form to another has always been an area of continuous development. However, the recent developments are endorsed to exploring efficient means of single stage AC-AC conversion. Eliminating the energy loss involved in two stage AC-AC conversion has been the focal point for researchers these days. Thus, the present study is devoted to presents the most wanted ...
متن کاملA Direct Power Feeding System for AC Railway Networks Using Modular Multilevel Converter
Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...
متن کاملDiode-Clamped Based Indirect Matrix Multilevel Converter Topology
This paper presents a novel sparse matrix converter configuration that needs no bulky energy storage capacitors or inductors, and employs only unidirectional power semiconductor switches. The source side bridge is switched at the line frequency and therefore, this allows the use of the low speed high power rating switches. This feature and the use of diode-clamped multilevel topology at the out...
