Power adapter

A power adapter to receive at least one input power and transform to DC primary output power, comprising:

• a power factor correction circuit connecting to an AC input end to receive an AC input power and modulating the power factor of the AC input power to deliver a modulated power;
• an isolation voltage step-down circuit connecting to the power factor correction circuit to receive the modulated power and modulating the modulated power to a lower voltage to deliver a modulated lower voltage power;
• a switch voltage regulation circuit connecting to the isolation voltage step-down circuit to receive the modulated lower voltage power and having a determined output level to transform the modulated lower voltage power to output a determined power;
• and
• a voltage stabilization circuit connecting to the switch voltage regulation circuit to modulate the determined power to become the primary output power sent to a primary output end and receive potential alterations of the primary output end and modulate the potential of the primary output power.
