본 논문에서는 스위칭 소자를 줄이기 위한 새로운 Z-소스 인버터의 구조와 PWM 펄스 제어 방법에 대하여 제안하였다. 개선된 Z-소스 인버터는 Z-네트워크가 DC전압과 인버터 사이가 아닌 인버터 뒷단과 접지 사이에 연결되며, 이러한 개선된Z-소스 인버터는 커패시터 돌입 전류 제한 기능과 커패시터 전압 스트레스가 작은 장점을 가지고 있다. 개선된 Z-소스 인버터에서 스위치를 6개에서 4개로 줄이는 새로운 형태의 스위치 저감형 Z-소스 인버터의 Topology를 제안하고, 제안된Topology에 적합한 PWM 제어 방법을 개발하였다. 제안된 방법은 PSIM 시뮬레이션을 통해 특성과 성능을 확인하였다
Abstract
In this paper, we propose a new Z-source inverter structure to reduce switching elements and PWM pulse controlmethod. Z-network is connected between the inverter backplane and ground, rather than between the DC voltage and theinverter in an improved Z-source inverter. And the improved Z-source inverter has the advantages of limiting thecapacitor inrush current and reducing the capacitor voltage stress. We have proposed a topology of a new type ofswitch-reduced improved Z-source inverter that reduces the number of switches from six to four in an improvedZ-source inverter and developed a PWM control method suitable for the proposed topology. The characteristics and theperformance of the proposed method were verified by using PSIM simulation.
