Abstract

This paper discusses the transient responses of switching mode power supplies (SMPS) under a lightning surge. These devices are normally used in fluorescent lighting, personal computers and other appliances. In this paper the circuit models of switching mode power supplies are developed by taking into account both the nonlinearity and the parasitic effect of SMPS components. These models are verified experimentally by comparing the surge current in the devices under a voltage surge. It is found that the surge current primarily arises from capacitor charging caused by the surge voltage. These devices can be then represented simply by capacitor-charging circuits in the analysis of lightning surges, particularly for the discussion of load effect. It is noted that the currents under common-mode and differential-mode surges are significantly different in magnitude and waveform. It is also noted that the supply circuit could have a significant effect on the surge current if the circuit impedance is comparable to the choke impedance.
雷电浪涌作用下开关电源的瞬态响应
本文讨论了开关电源在雷击浪涌作用下的瞬态响应。这些装置通常用于荧光灯、个人电脑和其他电器中。本文考虑了SMPS器件的非线性和寄生效应,建立了开关电源的电路模型。这些模型通过比较在电压浪涌下器件的浪涌电流进行了实验验证。研究发现,浪涌电流主要是由浪涌电压引起的电容器充电引起的。在雷击浪涌分析中,这些器件可以简单地用电容充电电路表示,特别是在讨论负载效应时。值得注意的是,共模和差模浪涌下的电流在幅度和波形上有很大的不同。还需要注意的是,如果电路阻抗与扼流圈阻抗相当,则电源电路可能对浪涌电流产生重大影响。
