Patent ID: 10608466

Abstract:
A power distribution system in a datacenter generates and distributes a pulsed direct current (DC) voltage, instead of alternating current (AC) power or DC power. The system includes an uninterruptible power supply (UPS) and a breaker and may include multiple UPS's and multiple breakers. The UPS is configured to receive an AC voltage. The UPS includes a rechargeable battery and a pulsed DC circuit that generates the pulsed DC output voltage to drive a load external to the UPS. The pulsed DC output voltage comprises a periodic waveform including an on phase and an off phase. The UPS generates a timing signal indicative of occurrence of the off phase of the pulsed DC output voltage. The breaker provides the pulsed DC output voltage from the UPS to the load and decouples the pulsed DC output voltage from the load during an off phase upon detection of a fault condition.
