Introduction Voltage impulse generators, commonly referred to as Voltage Spike Generators, are crucial tools in electromagnetic compatibility (EMC) testing. These devices simulate high-energy voltage spikes or transients that electrical equipment might encounter during operation, such as those caused by lightning strikes, switching operations, or power-line crosses. Voltage impulse generators are used to assess the performance and robustness of electronic components and systems under these extreme conditions. This article explores the principles behind voltage impulse generators, their applications, and a detailed review of the LISUN DO160-S17 Voltage Spike Generator, a leading model designed to meet industry standards for testing and compliance. 1. Overview of Voltage Impulse Generators Voltage impulse generators are designed to produce transient voltage spikes that simulate the surges and spikes seen in real-world electrical environments. These transients, often in the form of fast-r...
