A power management device and a management method thereof are provided. The power management device includes a switch, a detection circuit and a controller. The switch receives an external power. The detection circuit receives an internal power and at least one operation power. The detection circuit determines whether at least one of the internal power and the operation power is in a preset specification range or not to generate a protection activate signal. The controller sets a protection flag according to the protection activate signal, and generates a control signal according to the protection flag by executing an application program. The controller transmits the control signal to turn off the switch.

Power management device and management method thereof

A multi-power management system and an operation method for the multi-power management system are provided. The multi-power management system includes multiple adapters and a power supply circuit. The adapters respectively provide multiple powers. The power supply circuit receives multiple input power values of the adapters, and calculates multiple input power value contribution ratios of the adapters according to the input power values. The power supply circuit further provides a control signal according to a sum of the output current values of multiple output current values of the powers and the input power value contribution ratios. The adapters adjust the output current values and multiple output voltage values respectively in response to the control signal.

Multi-power management system and operation method thereof

An electronic apparatus is provided. The electronic apparatus includes a controller, a first trigger circuit, a switch unit and a logic circuit. The controller provides a setting signal. The first trigger circuit provides a trigger signal according to at least one of first trigger situations. The switch unit is connected to a power input terminal. The logic circuit adjusts a switching signal according to the setting signal and the trigger signal. The switch unit decides whether to provide an input voltage at the power input terminal to the electronic apparatus according to the switching signal.

Electronic apparatus

An electronic device including a solar cell, an energy storage unit, a control unit, and a controlled unit is provided. The solar cell converts light energy to electric energy. The energy storage unit performs charging by the electric energy. The control unit determines the intensity of the light energy according to an energy value of the electric energy and generates a correction signal accordingly, wherein the energy value is a current value or a voltage value. The controlled unit controls a characteristic parameter according to the correction signal.

Electronic device and control method thereof

A power conversion apparatus is provided. The power conversion apparatus includes an AC to DC adapter, an input port, a power conversion control unit, and a restart circuit. The AC to DC adapter converts an AC input voltage into a DC output voltage according to an external signal of an electronic apparatus and provides the DC output voltage to the electronic apparatus. The input port receives the AC input voltage through an AC input terminal. If the power conversion apparatus does not output the DC output voltage to the electronic apparatus, the power conversion control unit turns off the power conversion apparatus. If the restart circuit detects that an insertion action occurs on the input port, the restart circuit transmits a trigger signal to turn on the power conversion control unit in an off mode.

Power conversion apparatus for electronic apparatus

A power control module including a socket, a switch circuit and an interface control circuit is provided. A plug is adapted to be inserted into the socket, and the socket has a positive terminal, a first negative terminal and a second negative terminal. When the plug is inserted into the socket, a negative terminal of the plug sequentially contacts the first negative terminal and the second negative terminal. The switch circuit receives a power voltage through the positive terminal. The interface control circuit determines whether to generate a switching signal to the switch circuit according to a voltage level of the second negative terminal. When receiving the switching signal, the switch circuit outputs the power voltage.
