摘要
为了解决引信电子安全系统中高压反馈电路输入与输出端电气隔离的难题,提出了一种反馈控制电路方案.采用从高压变压器原边采样的反馈控制电路控制高压电容上充电电压的方法,解决了高压反馈电路输入与输出端电气隔离问题,并采用滤波方法消除漏感电压对反馈电容电压的影响.仿真实验结果表明,高压电容上电压被有效控制在2 kV,实现了高压变压器输入与输出端在电气隔离,且电路工作可靠.
A feedback control corcuit is presented to solve the problem of electric isolation between the input and output of high voltage feedback circuit used in the ESA of fuze. Sampling voltage from the original side of high voltage transformer can control the charge voltage of high voltage capacitance and solve the problem of electric isolation, and adopting filter to solve the problem of spike voltage in high voltage transformer. Simulation experiment results showed that the voltage of capacitance could be controlled to 2 kV, the input and output of high voltage transformer was effectively isolated and the control circuit worked reliably.
