What Causes DC Overvoltage in Inverter Modules?

Inverter module DC overvoltage occurs when the DC input voltage exceeds safe operating limits, threatening system stability. Imagine your electrical system as a highway – sudden voltage spikes are like trucks slamming their brakes, causing dangerous chain reactions. This issue particularly affects renewable energy systems and industrial applications where voltage fluctuations are common.

Top 3 Culprits Behind Overvoltage

• Grid instability during renewable energy integration (solar/wind)
• Improperly sized capacitors in DC links
• Faulty voltage regulation algorithms
