Abstract
A power supplying device having programmable current-balancing control includes at least two power modules in parallel. Each power module includes a power convertor, a current sensing component, a tuning circuit, a current-balancing control circuit and an output voltage controller. The power convertor provides power to a load via an output end. The current sensing component senses output current of the power convertor to generate a current sensing signal. The tuning circuit generates a tuning signal according to a control signaling from a communicating port. The current-balancing control circuit receives the current sensing signal and the tuning signal. The current-balancing control circuit generates a current-balancing signal according to the current sensing signal. The current-balancing control circuit generates a voltage control signal according to the tuning signal. The output voltage controller tunes an output voltage of the power convertor according to the current-balancing signal or the voltage control signal.
