| Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 101 === This thesis presents design and implementation of an interleaved bidirectional dc/dc converter for dc distribution system. A four-phase interleaved bidirectional dc-dc converter is adopted, which uses switching frequency modulation method for reducing circulating loss. This circuit is operated in SCM to reduce inductor volume and increase power density. Moreover, the circuit allows synchronous mode operation to achieve zero-voltage switching. A Reneses RX62T microprocessor realizes almost all of the functions, such as circuit protection, generation of PWM signals and A/D conversion, etc. If the load voltage drops below the nominal value, the converter operates in buck mode to regulate the load voltage. On the other hand, if the load power is higher than the desired value and the voltage at the battery side is low, the converter operates in boost mode. Finally, an interleaved bidirectional DC/DC converter is implemented to verify the feasibility and characteristic of the circuit.
