매트릭스 컨버터 토폴로지를 이용한 DC/DC 컨버터에 관한 연구

Abstract

Thesedays, propulsion system for ship has been developed to achieve high efficiency and environmental regulation. Emission regulation for atmosphere is hot issue for main propulsion. The countermeasures for satisfying environmental requirement are Emission reduction system, different Fuel type or Electric propulsion system. The efficiency of Electric propulsion system is based on the power converting system AC/AC, AC/DC, DC/AC, DC/DC

In case of DC/DC converter, there are different types of conventional DC/DC converter which use variable topologies to supply required DC voltage by using transistors and capacitors. However conventional DC/DC converter has limited operation method due to its configuration with diode.

This paper describes modeling and simulation of DC/DC converter using M atrix converter. This converter also has four quadrant operation, thanks to its function, the bidirectional operation is accomplished. The performance between Conventional DC/DC converter and Matrix topology DC/DC converter is the same. By having 8 equal switches, there are additional operation mode rather than conventional DC/DC converter. To control output voltage, DC/DC converter with Matrix converter uses pulse width modulation method. This topology nowadays widely applied in power distribution system, UPS, Solar power system and traction motor.

In this paper by using PSIM programme, the performance of stair case voltage characteristic, response characteristic with increasing voltage and reversal characteristic of voltage polarity are presented. And it will be compared with conventional DC/DC Converter
