Abstract

A simple source voltage clamped resonant link (SVCRL) inverter is proposed to clamp the DC link voltage to the input source voltage and reduce the current rating of resonant inductor. The current control of a permanent magnet synchronous motor (PMSM) using a predictive current control technique (PCCT) employing the SVCRL inverter is also investigated to overcome the disadvantage of the current regulated delta modulation (CRDM) control technique. By using the PCCT based on the discrete model of a PMSM and estimation of back EMF, the minimized current ripple with small number of switchings can be obtained. Finally, the comparative computer simulation and experimental results are given to show the usefulness of the proposed technique.

공진형 인버터의 직류 링크단의 전압 상승을 직류 공급 전압 이내로 제한하고, 공진형 인덕터의 전류 내량을 줄이기 위한 간단한 전압 억제형 공진형 인버터를 제안하였다. 이 전압 인버터를 영구 자석형 동기 전동기(PMSM)에 적용하여 이산 펄프 제어 방법중의 하나인 예측형 전류 제어 방법에 의해 실험과 시뮬레이션을 통하여 제안된 인버터의 동작을 보이고, 그 결과를 CRDM(Current Regulated Delta Modulation)방법에 의한 결과와 비교하였다.
