| 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: |
| The principle of self-excitation startup of APS（Auxiliary Power Supply） is analyzed，and the related calculation formulas are deduced. The startup conditions of APS are given，and the major influencing factors confirmed are startup resistance，startup capacitance，transformer primary inductance，transformer primary detection resistance，output capacitance，auxiliary capacitance and load. The conclusions obtained are：when the primary inductance，primary detection resistance or output capacitance is increased，the voltage setup time of output winding is increased while the voltage setup time and power-on time of auxiliary winding are decreased；when the startup capacitance is increased，the startup time of power supply and the voltage setup time of auxiliary winding are increased while the voltage setup time of output winding is decreased；when the load is increased，both the power-on time of auxiliary winding and the voltage setup time of output winding are decreased. The simulative results with PSPICE software and the experimental results of a two-tube flyback APS prototype with 300 ~ 2 500 V input and 24 V output validate the correctness of the conclusions. |
