Patent ID: 8687393

Claim:
A power converter module, comprising: a reference voltage generation unit, receiving an external voltage, and producing a reference voltage according to a direct-current input voltage with referring to an alternating current input voltage; a voltage loop control unit, receiving said external voltage and a first external current, and producing a reference current according to said reference voltage produced from said reference voltage generation unit; a current loop control unit, receiving said external voltage and a second external current, and producing a first public voltage according to said reference current produced from said voltage loop control unit, or directly assign said first public voltage as said reference current, an input voltage compensation unit, receiving an external direct-current voltage, and producing a second public voltage according to said first public voltage produced from said current loop control unit; and a pulse width modulation (PWM) generation unit, receiving said second public voltage produced from said input voltage compensation unit to produce a pulse width modulation signal, wherein said pulse width modulation signal is provided to an external pulse width modulation driver, in order to drive an external switch unit, and further produce an output power to supply power to an external loading device, said external voltage is terminal voltage of said loading device or is a voltage related to said terminal voltage, said first external current is a switch output current of said switch unit or is a current related to said switch output current, said second external current is a loading current of said loading device or is a current related to said loading current, and said external direct-current voltage provides power to said switch unit.
