Dynamic voltage adjustment device and power transmission system using the same

摘要

The present invention discloses a dynamic voltage adjustment device for dynamically adjusting an output voltage of a power transmission system which generates the output voltage according to a feedback signal and a reference signal and transmits the output voltage to a remote load via a transmission line to generate a load current. The dynamic voltage adjustment device comprises a first signal terminal, for receiving a first signal corresponding to a forward transmission voltage drop of the transmission line; a second signal terminal, for receiving a second signal corresponding to a reverse transmission voltage drop of the transmission line; a third signal terminal for receiving a reference voltage; a feedback circuit, for generating a feedback signal according to the first signal; and a adder circuit, for generating the reference signal according to the second signal and the reference voltage.
