Effective Design Techniques for Signal and Power Supply Isolation

Today, more than ever, electronics designers face a common set of goals: achieving higher throughput, higher resolution, more efficient systems and reduced time to market. In fields such as industrial automation, medical electronics or telecommunication systems, it is often necessary to electrically isolate multiple signals to enable sub-systems to share data or control signals without allowing noise or high voltages to interfere with system integrity and safety.

Isolating signals is not enough to provide true isolation from noise and high voltages – the power supplies need to be isolated too. Designing an isolated power supply is often something that takes specialized skills and experience. It costs precious time and multiple iterations to get it right.
