摘要
对DC/DC变换器无均流线均流控制方法进行了研究。利用变换器输出端传递的交流信号来实现均流控制具有其它均流控制方法所不具备的优点,非常适用于大量模块并联时的均流控制。对采用这种均流控制的并联电源系统进行了介绍,并对均流控制方法的基本原理进行了详细的分析。为验证这种控制方法,对采用3个模块的并联系统进行了仿真试验。
A current share method for paralleling the DC/DC converter without interconnection is presented in this paper.The technique uses the AC signal on the output line to realize current share control.The method has some merits which are not in possession of the other current share methods and is suit for current share control with great number of module parallel converter system.The parallel converter system using the proposed control method is presented ,and the basic principle of this control method without control interconnection is analyzed in detail.Simulative and practical implementations of this method are addressed and the experimental evaluation based on a three modules prototype system is also presented to validate the method.
