Steady-state analysis of a series-resonant DC-DC converter with a bipolar power flow

A time-domain analysis for the steady-state model of a series-resonant power interface for both step-up and step-down modes is presented. The exchange of electrical energy between a source and the resonant circuit in order to stabilize the stored electrical energy is defined. The characteristics of a series-resonant converter with bilateral power flow are presented in normalized form, described by the output characteristics. The results obtained in a four-quadrant motor drive illustrate the characteristics of a high-frequency power interface.<
