Why does a power supply need isolation?

Isolation is often required to prevent operator contact with dangerous voltages. Transformers used within power supplies function as a safety isolation transformer. Power supply designs must often accommodate loads at different potential voltages than the source. Isolation is often required to achieve the potential level shifting.

How do you isolate a power supply?

There are at least three methods for achieving isolation in power supplies: The most obvious form of power supply isolation is simple physical separation — used when there is no electrical, magnetic, or thermal interaction desired. The separation may employ different types of dielectric mediums between the conducting surfaces.

What is a power supply isolation transformer?

Electronic power supplies commonly process dangerous voltages with low impedances. Isolation is often required to prevent operator contact with dangerous voltages. Transformers used within power supplies function as a safety isolation transformer. Power supply designs must often accommodate loads at different potential voltages than the source.

How do you isolate a power output from a source?

The only way to properly isolate a power output from its source (and hence from any other power output on the same source) is with a transformer. The only way to use a transformer is with AC.

Does a power supply need galvanic isolation?

When designing a power supply, the first question to answer is whether or not galvanic isolation is required. Galvanic isolation is used for multiple reasons. It can make circuits safer, it allows for floating system operation, and it prevents noisy ground currents from spreading through different electronic devices in one circuitry.

How does an uninterrupted power supply work?

Most uninterrupted power supplies sold for computers 'switch' power, running a small inverter when power is interrupted, then switching back to 'normal' power when it's back on. This one simply produces AC power with a continuous duty inverter and assumes some system (s) will charge the DC battery supply it requires faster than it consumes it.
