다중 H-브릿지 인버터의 입력전류특성
Line Current Characteristics of Multilevel H-Bridge Inverters
초록
Recently, multilevel H-bridge inverters have become more popular in medium to high power ac drive applications. One of significant advantages of them is low harmonic contents in their input line currents thanks to the transformer with multiple phase-shifted secondary windings. This paper attempts to provide basic guidelines for the design of the phase shifting transformer windings and theoretical analysis of input line current harmonics.
