Today we have excellent motor drive system using high frequency carrier PWM control voltage source inverter with vector control strategy. In the other hand, we have met serious problems caused by high frequency switching. PWM Cyclo-converter called Matrix converter is expected as the new strategy possible to improve these problems and add some more convenient features suitable for new drive system with system integration. In this paper, we will introduce the background of this development and features of this converter from our research, additionally introduce remarkable active promotions for this converter as a survey.

A FPGA based delta modulated single phase matrix converter has been developed that may be used in both cyclo-converters and cyclo-inverters. This converter is ideal for variable speed electrical drives, induction heating, fluorescent lighting, ballasts and high frequency power supplies. The peripheral input-output and FPGA interfacing have been developed through Xilinx 9.2i, to generate delta modulated trigger pulses for the converter. The controller has been relieved of the time consuming computational task of PWM signal generation by implementing the method of trigger pulse generation in a FPGA by using Hardware Description Language VHDL in Xilinx. The trigger circuit has been tested qualitatively by observing various waveforms on an oscilloscope. The operation of the proposed system has been found to be satisfactory.

본 논문은 전력전자회로에서 많이 사용되고 있는 가장 범용적이고 강력한 시뮬레이터인 PSPICE와 MATLAB에 적용하여 소자를 모델링하여 보다 쉽게 이해하고, 다양한 제어기술을 적용시킬 수 있도록 미시적인 IGBT, 거시적인 IGBT, PWM 발생기 그리고 유도 전동기를 라이브러리화 하여 모델링의 타당성을 해석하였다. 미시적인 IGBT 모델의 소자특성을 실험을 통해 모델링의 정확성을 입증하였으며, 거시적인 IGBT모델은 사이클로 컨버터와 유도 전동기의 부하를 가진 전압형 PWM 인버터에 적용시켜 시뮬레이션 하였다.
