AC 220V to DC transformer ACDC conversion is to convert alternating current into stable direct current through rectification and filtering through the rectifier circuit.
AC power supplies can easily convert voltage (step-up, step-down) by using a transformer.
High voltage/low current can be maintained during power transmission, reducing voltage drop (I2R loss).
It can easily convert AC power to DC power, and it is easy to supply power to DC drive equipment.
