AC DC converter founction
the main functions of the ac dc power supply module has five categories, respectively is isolation founction, voltage transformation, 
protection functions, noise reduction founctions, voltage regulator founctions.
A. Isolation

1. Noise isolation:        (analog circuit and digital circuit isolation, strong or weak signal isolation) 
2. Saftey isolation: Consultative services isolated \ IGBT drive, surge protection, lightning protection of medical electronic equipment (such as the human body contact isolation protection)
3. Earth loop to eliminate: remote signal transmission, distributed power supply system

B. Switching voltage
Step-up, step down transformation, AC/DC conversion (AC/DC, DC/AC) \ polar transformation (positive and negative polarity conversion, single power supply and the positive and negative power conversion, single power supply and power conversion)
C. Protection
Short circuit protection, over voltage protection, under-voltage protection, over-current protection, and other protection
D. Noise reduction
active power filter 
E. Voltagestabilizing
