1. Isolation:
1. Noise isolation: (isolation of analog circuits and digital circuits, isolation of strong and weak signals)
2. Safety isolation: strong electricity Weak current isolation\IGBT isolation drive\surge isolation protection\lightning isolation protection (such as isolation protection for medical electronic equipment in contact with the human body)
3. Ground loop elimination: remote signal transmission\distributed power supply system
2. Voltage conversion:
Boost conversion \ buck conversion \ AC/DC conversion (AC/DC, DC/AC) \ polarity conversion (positive and negative polarity conversion, Single power supply and positive and negative power supply conversion, single power supply and multiple power supply conversion)
3. Protection:
Short circuit protection, overvoltage protection, undervoltage protection, overcurrent protection, other protections
4. Noise reduction:
Adopt active filtering
5. Voltage stabilization:
AC mains power supply\remote DC power supply \Distributed power supply system\battery power supply
