Abstract: A power system including power devices connected in parallel and an allocation bus is provided. Each power devices includes an allocation signal pin, a power unit and a control unit. The control unit controls a logic level of the allocation signal pin based on an operation status of the power unit. The AND logic operation performed on the logic level of the allocation signal pin of each of the power devices results in the logic level of the allocation bus. One of the power devices is set to a master mode through a first arbitration. The other power devices monitor the operation status of each other and a status of the allocation bus. Through a second arbitration, one of the power devices under a first operation status is set to a standby mode.

Abstract: An electronic apparatus includes a converting circuit and a first control circuit. The converting circuit converts an input voltage to an output voltage. The first control circuit compares a feedback signal representing the output voltage with a target voltage to generate an error voltage. When the electronic apparatus is on a starting-up status and the error voltage is not greater than a threshold voltage, the first control circuit outputs a first driving signal to drive the converting circuit according to the error voltage. When the electronic apparatus is on a starting-up status and the error voltage is greater than the threshold voltage, the first control circuit stops outputting the first driving signal. A frequency of the first driving signal is determined according to the error voltage.

Abstract: A power system including power devices connected in parallel and a wake-up bus is provided. Each power devices includes a wake-up signal pin, a power unit and a control unit. The control unit controls a logic level of the wake-up signal pin based on an operation status of the power unit. The AND logic operation performed on the logic level of the wake-up signal pin of each of the power devices results in the logic level of the wake-up bus. The control unit of each of the power devices monitors the logic level of the wake-up bus. When the logic level of the wake-up bus is at a second logic level, at least one power device under a standby mode is switched to an operation mode.
