| 摘 要： | 提出了一种推挽式电路采用耦合电感并联均流的方案，在等效工作电路的基础上，列出了电路并联工作的状态方程，推导出耦合电感作用下等效电阻和漏感偏差对均流度的解析公式。设计了一种5000W的升压电路，直流输入在90VDC-200VDC的范围内，直流输出稳定在350VDC，采用两路推挽电路并联。通过实验，验证了该方法的有效性。

| Abstract: | A new resonant push-pull converter in parallel with coupled inductor is proposed. Based on the equivalent circuit, the state equation is described. And then the effect of mismatch of the equivalent resistor and leakage inductor on sharing current is derived. The key design problem of the resonant converter is discussed. A boost current of 5 000 w is designed with the DC input of 90 V - 200 V and the DC output of 350V by means of two Push-pun Converters being parallel connected. Validity of the method is verified by the experiment. |
