LLC谐振电源多路输出反馈电路的控制设计

Control Design of Multiple Output Feedback Circuit for LLC Resonant Power Supply

开关电源多路输出反馈,多路输出采样调节PWM脉冲宽度,不仅考虑到每路输出之间的影响,还充分考虑负载调整率,使得输出每路电压能够在不同输出功率的时候,保证输出电压稳定,实现多路对称输出。

Multi-output feedback of switching power supply and multi-output sampling adjust the pulse width of PWM, not only considering the influence between each output, but also fully considering the load adjustment rate, so that the output voltage of each circuit can be stable at different output power, and achieve multi-channel symmetrical output.
