摘要： A resonant circuit has two parallel resonant branches and one assistant inductor connecting the two resonant branches. Each resonant branch has a series capacitor and a series inductor connected in series. The other end of the series inductor is for connecting to a primary side of a transformer unit. The resonant circuit can provide two characteristic resonant frequencies fr and fm, so that a resonant power converter using the resonant circuit has an operating frequency fs that satisfies fs>fr or fm
