This thesis is aimed to develop a bi-directional resonant converter with the flexible capability of supplying-power and modular expansion. By considering integrating different energy-storage for micro-grid applications, the study is focused on developing the bi-directional power transfer technique as well as hybrid power supply in anticipation of increasing the flexibility of power delivery. At the terminal of the input source of this proposed bi-directional multiple-input buck-boost converter, it presents the capability of modular expansion, through which each power module can be independently controlled. This converter is further combined with a full-bridge inverter and symmetrical resonance architecture so as to reach the requirements of bi-directional power delivery and determine different combinations of supplying-power under various load scenarios. To confirm the feasibility of this proposed system, the circuit is hardware-realized with measurements. Test results indicate that this proposed method exhibits the capability of bi-directional power delivery and modular expansion, which is of practical values for the application considered.
