Why Power Modules Must Go Through the “Test of Reactive Power Aging”

Reactive power aging is a critical reliability screening process for power modules before shipment. By applying rated voltage and controlled reactive current, modules are subjected to real electrical and thermal stress without excessive energy consumption. This accelerated aging method exposes latent defects early, significantly reducing initial failure rates and ensuring long-term stability in applications such as home appliances, new energy vehicles, and power grid systems. At KOE ELECTRONIC, reactive power aging plays a key role in delivering high-reliability power semiconductor solutions.
