Abstract

On the condition of f_s <; f_r/2, series-resonant converter has the characteristics of constant-current linear charging for small capacitance loads and soft-switching, and six kinds of models in one switching period are analyzed, and formulas of resonant current and resonant voltage are given. By utilizing the constant-current linear charging just like "average charging" for voltage-doubling rectifier, along with controlling ways of PAM and PFM, a set of soft-switching high-voltage DC power supply is manufactured, and designing processes of power supply and test results are given.
