摘要（英）：

The invention discloses a supercapacitor energy storage system based bidirectional DC/DC converter topology. The bidirectional DC/DC converter topology comprises a supercapacitor energy storage unit and a cascading bidirectional Buck/Boos-LLC DC/DC converter, wherein the supercapacitor energy storage unit is connected with the cascading bidirectional Buck/Boos-LLC DC/DC converter for realizing energy storage and energy release outwardly; and the cascading bidirectional Buck/Boos-LLC DC/DC converter formed by a bidirectional Buck/Boost DC/DC converter and a bidirectional full-bridge LLC resonant DC/DC converter that are connected in series can perform power bidirectional flow according to requirements of an external application system. According to the bidirectional DC/DC converter topology, PWM control on a switch tube in a power converter is carried out through the voltage and current real-time detection in the bidirectional Buck/Boost DC/DC converter and the bidirectional full-bridge LLC resonant DC/DC converter, so that the output power of the bidirectional DC/DC converter can be stabilized, the stable regulation of voltage can be realized, and the energy storage efficiency and the system reliability of the supercapacitor energy storage system are improved effectively.
