| Abstract: | Resonant bi-directional DC/DC Converter has character of low switching loss and suitable for high frequency application. This paper discusses frequency tracking control of resonant bi-directional DC/DC converter to achieve low circulating current of series resonant converter besides ZVS on and low current off of the switches. In the paper the method of frequency tracking control is analyzed, the closed control loop is also designed with frequency tracing control. Besides, one optimized method for designing control angle is proposed aiming at improving efficiency of the converter and the zero crossing detecting method of the control angle is proposed as well. Finally, the primary experiment is done on a 5kW prototype to verify the validity of the proposed theoretical analysis and design. |
