Isolation In Variable Frequency Drive And Power Supply Applications
Among all the parts used in electronic devices, the isolation component is undoubtedly one of the most important parts. This is especially the case in high voltage and high power applications. In variable frequency drive (VFD) and power supply designs, isolation components are typically used in both functional and safety isolation circuits to separate the low voltage control circuit from the high voltage power part, and keep interface circuits separate from circuits that are dangerous to touch.
