What Adverse Effects Do High Temperatures Have On Wide-range Voltage Regulators?

When using wide range stabilizer for ac in industrial power systems or large equipment, the internal electronic components and power devices may generate excessive heat due to ambient temperature or continuous high load operation. If this heat cannot be dissipated in time, the junction temperature of the devices will continue to rise, leading to a decrease in voltage regulation performance and even triggering thermal shutdown or internal protection mechanisms, causing the regulator to stop outputting power.

High-temperature environments also accelerate the aging of components such as semiconductor junctions and MOSFETs within the device. Increased temperature accelerates physical mechanisms such as electromigration and insulation layer degradation, causing long-term reliability issues and shortening the regulator's lifespan.

Heat accumulation affects the stability of internal control and voltage regulation circuits, causing output voltage drift or fluctuations. In extreme cases, the regulator may fail to maintain the set output voltage, adversely affecting downstream equipment.
