Description

technical field [0001] The invention relates to the technical field of circuits for generating electric pulses, in particular to a high-efficiency double-exponential electromagnetic pulse generating device. Background technique [0002] In the electromagnetic compatibility effect experiment, the injection method and the irradiation method are often used to simulate the two interference modes of conduction and radiation, and to evaluate the electromagnetic immunity / sensitivity of the electronic equipment or devices in the weapon equipment. The injection method is to Simulated interference sources such as double-exponential fast-edge electromagnetic pulses are directly injected into the device, circuit or device port under test. The advantage of the injection method is that the test conditions and steps are simple, and the device under test can obtain a certain voltage value and energy value by using a relatively low power source; moreover, compared with the irradiation method...

Problems solved by technology

However, the bipolar Marx circuit structure has to discharge to two loads separately, so the peak value of the output pulse voltage is halved, and the efficiency is low. If you want to output an output pulse with a high voltage peak value, the number of stages required is doubled, and the number of stages The increase of the frequency will inevitably increase the length of the Marx circuit, which will decrease the stability of the output pulse and increase the volume of the pulse generating device.
