Isolation:
1. Safety isolation: strong and weak electricity isolation\IGBT isolation drive\surge isolation protection\lightning isolation protection (such as isolation protection of medical electronic equipment in contact with the human body)
2. Noise isolation: (analog circuit and digital circuit isolation, strong and weak signal isolation)
3. Ground loop elimination: remote signal transmission\distributed power supply system
Protection:
Short circuit protection, over voltage protection, under voltage protection, over current protection, other protection
Voltage conversion:
"Boost conversion\step-down conversion\AC/DC conversion (AC/DC, DC/AC)\polar conversion (positive and negative polarity conversion, single power supply and positive and negative power conversion, single power supply and multiple power supply conversion) )
Voltage stabilization:
AC mains power supply\remote DC power supply\distributed power supply system\battery power supply
Noise reduction:
Active filtering
