开关直流电源并联运行在许多场合应用。每一路电源输出阻抗的不一致性使每一路输出电流难以均衡，影响了系统的可靠性。本文提出了一种双回路ＤＣ—ＤＣ变换器的控制方案。由于采用电压环（外环）和电流环（内环）两环结构的双回路控制模式，变换器输出电流得到了有效控制，便于多个ＤＣ—ＤＣ变换器输出直接并联，从而实现了模块化，具有一定的实用性
Switching DC power supply parallel operation in many applications. The inconsistency of the output impedance of each power supply makes it difficult to equalize the output current of each channel, affecting the reliability of the system. This paper presents a dual-loop DC-DC converter control scheme. Due to the dual-loop control mode of two-loop structure of voltage loop (outer loop) and current loop (inner loop), the output current of the converter is effectively controlled so that the output of multiple DC-DC converters can be directly connected in parallel, thereby realizing the modular , Has a certain practicality
