一种多路隔离驱动电路的设计与实现
资料介绍
在多输入直流变换器中，由于多个开关管不共地，因此常常需要设计多路隔离驱动电路。基于此，设计了一种多路隔离驱动电路，包括多路隔离驱动电源、基于改进传统N E555多谐振荡器实现的PW M 信号发生电路和基于T L P250实现的隔离电路。详细分析了各个部分的工作原理并给出相应的电路原理图。最后，通过实验验证了所设计电路的正确性和可行性。
Since many switches do not share a common ground in the multiple‐input dc‐dc converter ,isola‐ted driving circuit is usually needed .Due to this ,an isolated driving circuit with multi‐channel output is designed in this paper ,which includes an isolated driving power supplies with multi‐channel output ,a cir‐cuit producing PWM signal based on improved NE555 multivibrator and an isolated circuit based on TLP250 .Operating principle of every part is analyzed in detail and the corresponding schematic circuit is given .Finally ,the experimental results verify the correctness and feasibility of this driving circuit .
