An AC-DC power module is a power supply device that converts alternating current into direct current, usually consisting of a transformer, rectifier and filter.
Introduction to AC-DC Power Modules The AC-DC power module is a compact and high-efficiency power solution that converts ordinary power in urban, rural or other fields into the stable low-voltage direct current required by electronic devices.
A buck power module with in an adjustable buck-boost power module.
The principle of the step-down module is to change the duty cycle to achieve voltage reduction and voltage stabilization.
