| Abstract |
High electric power conditioners operating at high frequencies are receiving increasing attention. The application of series-resonant power converters and related converter circuits are now the state-of-the-art for low-power applications. Miniaturization of power converters for the submegawatt range operating at high frequencies is now an important development for compact, fast-reacting machine drives. Many applications do need to use a bilateral flow of power (four-quadrant operation). A time-domain analysis for the steady-state modeling of a series-resonant power interface for the step-up and the step-down mode is presented. The exchange of electric energy between a source and the resonant circuit in order to stabilize the stored electric energy is defined. The characteristics of a series-resonant converter with a bilateral power flow are presented in a 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. |
