Application of Pulsed High Voltage Generators in Electromagnetic Environment Simulation

With the rapid development of modern electronic technology, electronic devices are increasingly applied in fields such as military, communications, and aerospace. However, these devices are often affected by various electromagnetic interferences during operation. To ensure that electronic devices can operate stably and reliably in complex electromagnetic environments, it is crucial to conduct strict electromagnetic environment simulation tests. In this process, pulsed high voltage generators play an indispensable role.

Pulsed high voltage generators can produce high-voltage, short-pulse voltage signals, which can simulate various transient overvoltage conditions that electronic devices may encounter in actual operation. By applying these pulse voltage signals to electronic devices, their anti-interference capability, insulation performance, and reliability can be effectively evaluated.

In electromagnetic environment simulation, the application of pulsed high voltage generators is mainly reflected in the following aspects:

I. Simulating Lightning Overvoltage

Lightning overvoltage is one of the most common and destructive transient overvoltages in nature. Pulsed high voltage generators can produce high-voltage pulses similar to lightning overvoltage waveforms, used to simulate the operating conditions of electronic devices in lightning environments. Through this simulation test, potential weaknesses in the device can be identified in a timely manner, and corresponding protective measures can be taken to ensure the safe operation of the device in lightning environments.

II. Simulating Switching Overvoltage

Switching overvoltage is a transient overvoltage caused by switching operations, fault clearing, and other reasons in the power system. Pulsed high voltage generators can simulate these switching overvoltages and conduct endurance tests on electronic devices. Through testing, the risk of switching overvoltage that devices may encounter during normal operation can be assessed, and optimization designs can be performed to improve the operational stability of the devices.

III. Simulating Electromagnetic Pulse Interference

An electromagnetic pulse (EMP) is a phenomenon of extremely high-intensity, very short-duration release of electromagnetic energy. Pulsed high voltage generators can produce high-voltage pulses similar to EMPs, used to simulate the response of electronic devices when subjected to electromagnetic pulse interference. This test is of great significance for evaluating the anti-interference capability of electronic devices, especially in military and aerospace fields, where electromagnetic pulse interference may cause serious effects on the normal operation of devices.

IV. Safety and Reliability Testing of High Voltage Power Supplies

In addition to the above applications, pulsed high voltage generators can also be used for safety and reliability testing of high voltage power supplies. By applying high-voltage pulse signals to high voltage power supplies, the output characteristics and protection functions of the power supply under abnormal conditions can be tested for normal operation.

In summary, pulsed high voltage generators have broad application value in electromagnetic environment simulation. They can not only simulate various transient overvoltage conditions but also evaluate the anti-interference capability, insulation performance, and reliability of electronic devices. With the continuous advancement of technology and increasing application demands, pulsed high voltage generators will play an even more important role in future electromagnetic environment simulation tests.
