一种交错并联LLC电路的均流调节方法
摘要：
本发明公开了一种交错并联LLC电路的均流调节方法，交错并联LLC电路包括交错并联的复数条LLC支路，实时检测各LLC支路的电流差值或电压差值，得到误差因子e；根据误差因子e，通过负反馈调节各LLC支路的占空比D，改变各LLC支路的增益，实现交错并联LLC电路的均流调节。本发明通过实时检测各LLC支路的不均流差值，进行运算，得到占空比的调节量，能实现对不同并联LLC电路的均流控制。
摘要（英）：

The present invention discloses an interleaved parallel LLC circuit current-sharing regulation method. An interleaved parallel LLC circuit comprises an a plurality of interleaved parallel LLC branchesconfigured to detect current difference or voltage difference of each LLC branch to obtain error factors e; according to the error factors e, the duty cycle D of each LLC branch is subjected to negative feedback regulation to change the gain of each LLC branch so as to achieve current-sharing regulation of the interleaved parallel LLC circuit. The interleaved parallel LLC circuit current-sharingregulation method detects the non-current-sharing different of each LLC branch in real time and performs operation to obtain the regulation quantity of the duty cycles and achieve current-sharing control of different parallel LLC circuits.
