Abstract
A switching power supply includes an input terminal, a voltage converter, a feedback circuit, and a pulse width modulation (PWM) controller. The input terminal receives a first direct current (DC) voltage. The voltage converter transforms the first DC voltage into a second DC voltage and provides the second DC voltage to a load via transmission lines. The feedback circuit is configured for detecting voltage lost across the transmission lines. The PWM controller controls the voltage converter to adjust the second DC voltage according to the voltage loss.
