Making Isolation Safety Standards Work for You

Mark Cantrell, Analog Devices

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 to

Take Control of Your Power Supply

Bruce Haug, Linear Technology

Did you ever feel like it’s time to take control of your power supplies? If not, you should, since there is a growing trend to configure and monitor power supplies over a digital communications bus. This is frequently referred to as “Digital Power” or “Digital Power System Management” (DPSM). This te

Managing hold up/transparency time in high-reliability power supplies

Christophe Massenet, GAIA Converter

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 power int
