【摘要】：針對(duì)雙有源dc-dc變換器采用傳統(tǒng)單移相控制時(shí)存在環(huán)流功率以及電壓不匹配時(shí)電流應(yīng)力過(guò)大的缺點(diǎn),雙重移相控制備受青睞。本文首先分析了雙重移相控制的所有模態(tài)、并以其中一種模態(tài)為例分析了雙重移相控制的工作原理,分別分析推導(dǎo)得出單移相和雙重移相控制方式下雙有源dc-dc變換器的傳輸功率和電流應(yīng)力。在此基礎(chǔ)上,分析推導(dǎo)了雙重移相控制所有模態(tài)下電流應(yīng)力最小的條件以及最優(yōu)電流控制原理和實(shí)現(xiàn)方案,使雙有源dc-dc變換器工作在電流應(yīng)力最小狀態(tài),提高了效率。最后通過(guò)實(shí)驗(yàn)驗(yàn)證了最優(yōu)電流控制正確性和優(yōu)越性。
[Abstract]:Dual phase shift control is very popular in dual active dc-dc converters because of the disadvantage of excessive current stress when the power of circulation and voltage are not matched by conventional single phase shift control. In this paper, all modes of dual phase shift control are analyzed firstly. Taking one of the modes as an example, the working principle of dual phase shift control is analyzed, and the transmission power and current stress of dual active dc-dc converter under single phase shift control and dual phase shift control mode are derived respectively. The condition of minimum current stress in all modes of dual phase shift control and the principle and implementation of optimal current control are analyzed and deduced to make the dual active dc-dc converter operate in the state of minimum current stress. Finally, the correctness and superiority of the optimal current control are verified by experiments.
