Abstract: A system includes: a first converter for receiving a pre-stage input DC voltage from a power source, and providing a pre-stage output DC voltage including a first DC voltage or a second DC voltage; a modulator the modulator controlling the first converter; a second converter, coupled to the first converter; and a controller, the controller controlling an operation mode of the second converter and notifying the modulator about the operation mode of the second converter. The modulator and the controller receive an external voltage indication signal indicating whether the pre-stage output DC voltage is the first DC voltage or the second DC voltage. The modulator controls the first converter to output the pre-stage output DC voltage based on the voltage indication signal. The modulator notifies the controller about whether the pre-stage output DC voltage reaches a target level.
