技術說明

一種多相鏈結均流控制電路，包含：一電壓命令運算模組，用以接收一輸出電力信號的電壓所對應的數位值，且接收一預期數位參考值，並據以進行運算以得到一電壓控制力；一多相電流命令運算模組，用以接收第一至第m相偵測電壓各自所對應的數位值，並據以進行運算以得到第一至第m電流控制力；一控制力運算模組，用以接收該電壓控制力，及該第一至第m電流控制力，並據以進行運算以得到第一至第m脈波調變信號組來控制一多相電力轉換裝置，m≧3。 A simple current sharing control technique for the switching power supply is presented herein, whose basic concept is that the control effort created from the voltage loop is finely tuned by the control effort created from the current sharing loop based on the proposed phase link so as not only to obtain the desired output voltage but also to make the load current distributed among phases as evenly as possible. Such a control method is not only without any current sharing bus as compared with the traditional current sharing methods, but also suitable for multiple phases under the condition that any one phase among multiple phases fails. Moreover, based on phase link, there is no divider used, as compared with the traditional average current method, and hence, the number of logic elements in the field-programmable gate array (FPGA) can be reduced.
