A power output control module for power distribution is installed inside a power distributor that is connected to an AC power source and multiple electronic devices to control the AC power outputted to the electronic devices. The power output control module continuously detects whether the AC power inputted is normal. When the AC power source is disconnected by accident, a latch relay is controlled to switch to be open, so that the AC power source and the electronic devices are disconnected. This prevents the instantaneous surge current from damaging the electronic devices when the AC power source resumes its normal output and also increases the safety and reliability of electronic devices.

A shutdown controlling method is applied to a system that has a host computer, a PDU and multiple electric apparatus connected to the PDU. The PDU has multiple outlets and stores preset shutdown periods for the outlets respectively. The PDU communicates with the electric apparatus and obtains their required shutdown periods. When PDU is controlled to cut off an outlet, the PDU determines whether the preset shutdown period of the outlet is larger than the required shutdown period. If yes, the PDU cuts out the AC power of the outlet. If not, the PDU cancels the shutdown command and notifies the host computer. Therefore, a manager may update the preset shutdown period of the outlet to ensure that each electric apparatus has enough time to be safely shut down.

An uninterruptible power supply (UPS) system with energy feedback to chargers and sinusoidal output charges a battery pack through a first charger under a mains mode. Under a battery mode, the UPS boosts DC voltage outputted from the battery pack to a higher voltage level through a DC-to-DC conversion module, converts the DC voltage to a sinusoidal AC voltage through a DC-to-AC conversion module, and supplies the sinusoidal AC voltage to a load. When the load has energy storage elements and discharged energy occurs in a power supply loop, a micro-controller unit can control the discharged power to charge the battery pack through a second charger, thereby solving the issue of the discharged power from the energy storage elements of the load and enhancing the operational efficiency of the UPS.

An uninterruptible power supply having efficiency power conversion has an AC to DC power conversion circuit, a battery power conversion circuit and a control circuit. The AC to DC power conversion circuit is parallelly connected to the battery power conversion circuit to convert the AC power of an AC mains into a DC power and supply the DC power to a load. When the AC mains stably supplies power, the control circuit controls to activate the AC to DC power conversion circuit and supply power to the load through the AC to DC power conversion circuit only. As there is only one power conversion between the AC mains and the load, the power conversion efficiency can be enhanced.

A method of remotely controlling power distribution units enables the power distribution units to automatically transmit messages to a server once connected to the server via a network. When a user logs into a server and requests to remotely control the associated power distribution units, the user only needs to enter the serial numbers or identification data thereof. The server then automatically searches for all power distribution units owned by the user, and provides a group management interface. The user can then group the power distribution units according to their locations or their properties in order to control the on and off thereof. Without knowing the IP addresses of the power distribution units, the user can readily control the power distribution units at different locations remotely.

A control method of an uninterruptible power supply (UPS) for extending a discharge time under a no-load condition instructs a battery of the UPS to discharge by repeating an alternate on and off cycle when the UPS enters a battery mode and after a no-load condition continues over a period of time so that the UPS alternately and repeatedly discharges and stops discharging based on the alternate on and off cycle, and detects if the no-load condition is not present during the discharging period. If not present, the battery is restored to continuously discharge. Additionally, the discharge voltage can be reduced during the discharging period to alleviate the power discharged under the no-load condition. Accordingly, the control method can reduce to discharge under the no-load condition and further extend a discharge time under a no-load condition.

A universal series bus (USB) power supply has a DC power source, a USB power interface and a voltage modulation module. The USB power interface is for connecting to an electronic device that stores a default D+ voltage and a default D− voltage. The voltage modulation module connects to and outputs signals to the D+ and D− terminals of the USB power interface. If voltage levels of the output signals are not respectively identical to the default D+ and D− voltages, the voltage modulation module changes the voltage levels of the signals output to the D+ and D− terminals of the USB power interface until the voltage levels of the output signals are respectively identical to the default D+ and D− voltages. Therefore, the USB power supply may be applied to any kind of electronic device that is charged over a USB interface.
