Research on Parallel Current Sharing Driving Power Supply Based on High Power LED

探究一种主从法控制的交错并联Buck电路来实现小功率电源的并联均流,主要用于驱动大功率LED,利用仿真软件来检验电路是否实现了均流控制。分析认为,与传统线性电源相比,通过主从法控制的交错并联Buck电路对多组电源并联具有均流控制效果。

An interleaved parallel Buck circuit controlled by master-slave method is explored to achieve parallel current equalization of small power supplies,mainly for driving high-power LEDs,and simulation software is used to check whether the circuit achieves current equalization control.The analysis concludes that the interleaved parallel Buck circuit controlled by master-slave method has the equalization control effect for multiple power supplies in parallel compared with the traditional linear power supply.
