| 英文摘要: |
| A kind of charging power supply module with high reliability for a non attendant intelligent substation is designed. LLC resonant converter with medium and small power is chosen as the main power topology for its advantages of high conversion efficiency and power supply quality. The design process is presented in detail and several schemes on improving the reliability are also proposed, such as, charging scheme of the battery array and failure protection. Finally, prototype is set up and the experimental result verifies the feasibility and accuracy of the proposed design method. |
