AC stands for Alternating Current.
AC power supply role?Isolation
1, safety isolation: strong and weak power isolation \ IGBT isolation drive \ surge isolation protection \ lightning isolation protection. (Such as human contact with the isolation of medical electronic equipment protection)
2, noise isolation: (analog circuitry and digital circuitry 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, overcurrent protection, and other protection
Voltage Conversion
Boost Conversion\Buck 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)
