To safeguard power supplies and their connected devices against surges, it is necessary to incorporate some kind of internal or external surge protection circuit. There are primarily two types of surge protection circuits – clamps and crowbars. Voltage clamps work by preventing the voltage from surpassing the selected clamping voltage.
A power surge or a sudden and brief increase in voltage or current in an electrical circuit, can be caused by several factors, including: Lightning strikes: One of the most common causes of power surges is lightning strikes. When lightning strikes power lines, it can send a surge of electricity through the lines and into homes and buildings.
Voltage surges are a concern of many mains powered devices. Surges can damage power supplies and the devices they power if not properly designed for the intended environment.
This means that DC power supplies must be designed and tested to withstand the specified level of voltage surge to meet the IEC 61000-4-5 standard. Meeting the IEC 61000-4-5 standard is crucial for power supplies because it ensures that they can withstand voltage surges caused by lightning or other electrical disturbances.
A power surge is a sudden and brief increase in voltage or current in an electrical circuit. It can occur when the flow of electricity is interrupted and started again, causing a sudden change of energy.
Multiple factors including location, cabling, and the level of surge protection applied (internally or externally) to the power supply input will affect the intensity and magnitude of the surge voltage at the power supply input.

Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform. Power converters also often have inrush currents much higher than their steady-state currents, due to the charging current of the input capacitance. The selection o…
In other words, remove any power strips, battery backups, or other power distribution devices between your PC and the wall outlet. If your computer starts getting power after doing this, something that you removed from the equation is the cause of the problem.
