Abstract:
The present invention provides a power system and controlling method thereof. The power system includes: pulse width modulation (PWM) power source, voltage detection unit, current detection unit and feedback signal generation unit. PWM power source receives external DC input, performs PWM on received external DC input, and supplies PWM output obtained through PWM from the DC output terminal to a device expecting power supply. Voltage detection unit detects voltage amplitude of PWM output. Current detection unit detects current amplitude of PWM output. Feedback signal generation unit generates feedback signal and supplies generated feedback signal to PWM power source. PWM power source adjusts the voltage amplitude and current amplitude of the PWM output based on the received feedback signal.
