Problems solved by technology

[0020] The technical problem to be solved by the present invention is to overcome that the existing Crowbar impulse current generator can only test voltage switching characteristic components such as gas discharge tubes and air gaps, and cannot test voltage clamping characteristic components such as piezoresistors with large discharge currents. Devices, and the working voltage is too high, it is difficult to implement in general enterprise laboratories and other shortcomings, provide a long-duration impulse current generator that can be easily matched with various voltage clamping characteristic components, and at the same time The operating voltage of the device is reduced to the level that is easy to implement in general enterprise laboratories

Embodiment 1

[0038] attached Figure 5 Is an embodiment of the present invention, and in this example, the current control device KI is a freewheeling diode D, among which DUT is a test object, L is a waveform inductance, C is an energy storage capacitor, and K is a discharge switch of the energy storage capacitor, The charging power supply is any form of DC adjustable power supply. When working, first charge C with the required voltage Uo from the charging power source, then press the start button AN, switch K1 through the control circuit KZ, and discharge the capacitor C to the inductor L. After the charge stored on C is discharged, When the inductance L generates a back EMF, a current is pushed to flow through the object under test DUT and the freewheeling diode D, and the waveform of the current is determined by the impedance characteristics of the inductance L and the DUT.

Embodiment 2

[0040] attached Figure 6 It is another embodiment of the present invention. In this example, the current control device KI is the trigger ball gap G2, and the capacitive discharge switch is the trigger ball gap G1. Press the start button AN, the trigger circuit Tr1 outputs an ignition pulse to G1, so G1 breaks down and conducts, and the capacitor C discharges to the inductor L. After the charge stored on C is discharged, the inductor L generates a counter electromotive force. This counter electromotive force makes The trigger circuit Tr2 outputs an ignition pulse to G2, so G2 breaks down and conducts, and the inductance L pushes a current to flow through the DUT and the ball gap G2 to form the required current wave. The diode D in the figure blocks the discharge voltage of the capacitor C from entering Tr2.

Description

technical field [0001] The invention relates to an impulse current generator, especially a high-peak long-duration impulse current generator whose output current is only formed by the energy leakage of an inductance. It is mainly used for simulating the direct effect of lightning or other similar high-energy current effects. test. Background technique [0002] With the increasing informatization of human society, information technology products have rapidly penetrated into all aspects of the national economy, national defense security and people's lives, and the number of products in use has increased rapidly. [0003] The basis of modern information technology products is the integrated circuit chip. While the chip is becoming more and more integrated and its functions are becoming more and more powerful, the internal lines and the spacing between the lines are getting finer and finer. As a result, it is resistant to surge currents. The ability of / voltage is getting lowe...
