Introduction In today’s industrial landscape, ensuring the resilience of electronic devices against power disturbances is paramount. These disturbances, including voltage dips and short-term interruptions, can lead to malfunctions and failures in sensitive equipment. Testing the immunity of such devices against these power anomalies is an essential part of compliance with various electromagnetic compatibility (EMC) standards. The voltage dip generator, such as the LISUN CSS61000-11 Voltage Dips and Interruptions Generator, plays a vital role in this testing process. Understanding Voltage Dips and Interruptions Voltage dips refer to short-duration reductions in the voltage supply, typically lasting from a few milliseconds to several seconds. These dips can result from various causes, including faults in the power grid, equipment startups, or electrical switching. Short-term interruptions, on the other hand, are complete losses of voltage for brief periods, which may occur due to similar...
