Abstract

A resonant DC link inverter that provides high efficiency with low noise for uninterruptible power supplies has been developed. This paper describes the noise radiation, efficiency, and output voltage characteristics of a prototype resonant DC link inverter. It has 300 V DC input, and 200 V (1φ) and 10 kVA AC output. The noise radiation level meets the CISPR Pub. 22 standard and its efficiency and output voltage characteristics make it usable for practical applications
