【摘要】：分析了辅助电源自激启动原理,推导了辅助电源启动相关公式,给出了辅助电源自激启动条件,确定了影响辅助电源启动的主要因素为启动电阻、启动电容、变压器原边电感、变压器原边检测电阻、输出电容和辅助电容及负载,并得出以下结论:原边电感或原边检测电阻或输出电容增加时,电源输出绕组建压时间增加而辅助绕组建压和供电时间减少;启动电容增加时,电源启动时间和辅助绕组建压时间增加而输出绕组建压时间减少;负载增加时,辅助绕组供电时间和输出绕组建压时间均减少。分别基于PSPICE仿真软件和300~2 500 V输入、24 V输出的双管反激辅助电源样机对影响辅助电源启动的主要因素进行了仿真和实验验证,结果表明上述结论正确。
[Abstract]:This paper analyzes the principle of Auxiliary Power supply starting, deduces the relevant formula of Auxiliary Power supply Start-up, gives the conditions of Auxiliary Power Auxiliary starting, and determines that the main factors that influence the Auxiliary Power Start-up are starting resistance, starting capacitance, transformer primary inductance. The output capacitance and the auxiliary capacitance and load of the transformer are measured by the original edge check, and the following conclusions are drawn: when the primary edge inductance or the original edge check measurement resistance or output capacitance increases, When the power supply output voltage increases, the auxiliary winding voltage and power supply time decrease; when the starting capacitance increases, the power supply start-up time and auxiliary winding build voltage time increase, while the output winding build voltage time decreases; when the load increases, the power supply start-up time and the auxiliary winding build voltage time decrease; when the load increases, The power supply time of auxiliary winding and the forming voltage time of output winding are reduced. Based on the simulation software of PSPICE and the prototype of dual-tube flyback auxiliary power supply with 300V 2500V input and 24V output, the main factors affecting the starting of auxiliary power supply are simulated and verified by experiments. The results show that the above conclusions are correct.
