摘要
介绍了采用UC3843设计的一款Boost升压电路。对电路设计过程给出了具体方法。并针对反馈电路中的电流反馈环节介绍了电流互感器反馈法。还讨论了如何从输出电容的选择上控制输出电压纹波,并给出了在不同输出电容值和电容串联等效电阻情况下的理论纹波大小和仿真纹波大小。
A Boost boost circuit designed based on the use of UC3843 was introduced. The design process of the circuit was introduced. A current transformer feedback method in the current feedback circuit of the feedback loop was used. In addition,the relationship of the output capacitor and the output voltage ripple were discussed. Study on the theory and simulation output ripple output ripple in different output capacitance and the capacitance equivalent series resistor case were discussed.
