摘要： An uninterruptible power supply having a controllable leakage current is disclosed. The leakage current is controlled by adjusting a switching speed (i.e., dV/dt rate) of switches in the output inverter (i.e. DC-AC converter stage). Leakage current can be reduced by reducing the switching speed (dV/dt rate) of the output inverter switches. In one embodiment, leakage current is held constant or moderated as output power decreases by reducing the switching speed (responsive to leakage current) as output power decreases. The switching speed can be adjusted by adjusting the gate resistance or gate voltage. Increasing the gate resistance or decreasing the gate voltage will cause a reduction in the switching speed, and increase in leakage current. Conversely, reducing the gate resistance, or decreasing the gate voltage will cause an increase in switching speed, and increase in leakage current. The present invention is applicable to any uninterruptible power supply having output inverter switches.

摘要： An uninterruptible power supply apparatus includes a switch, a first inductor, a direct current controlling unit, a first bridge arm, a second bridge arm and a third bridge arm. When the switch switches the first inductor coupled to an alternative current (AC) power, the AC power converts into a bus voltage via the first inductor, the first bridge arm and the second bridge arm, and converts into an output power via the second bridge arm and the third bridge arm. When the switch switches the first inductor coupled to a DC power, the DC power converts into the bus voltage via the DC controlling unit and the first inductor, and converts into the output power via the second bridge arm and the third bridge arm.

摘要： An uninterruptable power supply (UPS) system/method providing power line conditioning and power factor correction (PFC) that incorporates centralized battery backup energy storage architecture is disclosed. The system generally comprises an AC-DC power supply with active PFC (power factor correction) function, a battery transfer switch, an isolated battery charger placed between the utility power source and battery strings, battery strings connecting the battery charger and the battery transfer switch, EMI/Lightning circuitry that provides lighting/line surge protection as well noise suppression functions, and a controller monitoring the quality of the utility power source. Uninterruptable power for data centers is achieved in this context via use of the battery strings, battery transfer switch, battery charger, and controller system configuration. Disclosed methods associated with this system generally permit the UPS to operate in a distributed fashion in support of computing systems within data centers.
