In this article we will examine effective ways to use IEC (International Electrical Commission) safety standards to explore the limits of a design by figuring out what standards may apply to a problem amongst the hundreds available. The standards and supporting documents from the IEC are perceived as a burden

As soon as a power supply designer needs to comply with military standards, he might need to take into account the transparency or holdup requirement. Transparency requirement is the minimum amount of time during which input power can go away but the equipment is expected to remain operational. This
