摘要： When three phase AC voltages (Vi1 to Vi3) from a commercial AC power supply (51) become abnormal, a control circuit (6) of an uninterruptible power supply device provides an OFF command signal to first to third switches (1a to 1c), and causes first to third power converters (2a to 2c) to output first to third direct currents, respectively, and quickly extinguish arcs in the first to third switches (1a to 1c). On this occasion, polarities of the first to third direct currents are the same as polarities of currents (Is1 to Is3) flowing into the first to third switches (1a to 1c), respectively, and the sum of values of the first to third direct currents is 0.

摘要： According to an aspect, an electronic device includes a switching converter configured to generate an output voltage with a first voltage level from a battery voltage in a run mode of the electronic device. The switching converter is configured to generate the output voltage with a second voltage level from the battery voltage in a sleep mode of the electronic device. The second voltage level is less than the first voltage level. The switching converter includes a clocked comparator, and a voltage comparator. The switching converter is configured to generate the output voltage with the first voltage level in the run mode using the clocked comparator. The switching converter is configured to generate the output voltage with the second voltage level in the sleep mode using the voltage comparator.

摘要： Some embodiments of the inventive subject matter provide a system including a plurality of power supply units having AC inputs configured to be coupled to an AC power source and AC outputs coupled to respective first busses. Each of the power supply units includes an uninterruptible power supply (UPS) having an output configured to be coupled to the AC output of the power supply unit, a first switch configured to selectively couple the AC input to the AC output of the power supply unit, and a second switch configured to selectively couple the AC output of the power supply unit to a second bus. The system may further include at least one control circuit configured to control first and second ones of the power supply units to enable the first one of the power supply units to provide power to the first bus coupled to the second power supply unit from the first power supply unit via the second bus.

摘要： An un-interruptible power supply (UPS) with indication of battery internal resistance includes a processor, a display, a sensing module and a battery pack. The sensing module is connected to the processor and the battery pack. The processor is connected to the display, generates a reference internal resistance according to multiple internal resistances detected by the sensing module within a stable time after installation, generates a stable internal resistance according to an internal resistance of the battery pack detected by the sensing module after the stable time, compares the stable internal resistance with the reference internal resistance to generate a status of internal resistance of the battery pack, and instructs the display unit to display the status for user's timely awareness of the condition of the battery pack and prompt action when the performance of the battery pack deteriorates.

摘要： A thermostat includes a power stealing circuit selectively configured to provide power to the thermostat and to circuit(s) ancillary to the thermostat from power source(s) external to the thermostat, without requiring a common or neutral connection between the thermostat and the power source(s). Exemplary embodiments also are disclosed of a climate control system that includes such a thermostat. This thermostat can power-steal off of existing load wires (e.g., a W and/or Y terminal, etc.) and can provide power for a continuous backlight and/or other device (e.g., a remote sensor and/or low-power transceiver, etc.).

摘要： A power adapter (1) for cutting off standby power and a control method therefor are disclosed, the power adapter (1) comprising a power supply unit generating various kinds of power required for an electronic product (400) so as to supply the generated power through an adapter jack. The power adapter (1) comprises: a control unit (80) including at least one microprocessor (U1); a power switching unit (10) configured to cut off the power supplied to the electronic product and cut off a power supply to the power adapter when the power of the electronic product is turned “off” and a battery is fully charged or when the electronic product is disconnected, and to supply power under the control of the control unit (80); a current sensing unit (CT) configured to sense that the power of the electronic product is turned “off” and the battery thereof is fully charged; an electronic product connection sensing unit (50) for checking whether the electronic product is connected in a state in which power is cut off so as to provide the checking result to the control unit (80); a sleep power source unit (30) having a battery to be charged with power from the power supply unit (20) when the power is supplied, and configured to supply power only to the microprocessor (U1) and the product connection sensing unit (50) even when the power switching unit (10) is disconnected; a sensing power switching means (40) configured to supply operating power only during periodic checking of whether the electronic product is connected in a state in which power is cut off; and a sleep power sensing means for monitoring a voltage of the sleep power source unit (30) so as to prevent an operation error due to over-discharge of the sleep power source unit (30) when power is cut off. The power adapter of the present invention adds a circuit for the power adapter without a design change of the electronic product such that a conventional power supply jack of the electronic product can be connected and used as is.

摘要： A power supply system includes at least a first power supply module and at least one redundant power supply module. The at least one power supply module supplies power to an output terminal. The at least one redundant power supply module operates in a first state and in a second state. In the first state the second power supply module supplies power to the output terminal. In the second state the second power supply module provides standby power and operates in a burst mode (for example, such as a discontinuous conduction mode).
