Abstract
Power systems and methods for supplying direct current power to a server rack employ multiple power supply units. A method for supplying direct current power to a server rack includes receiving an alternating current (AC) power input. A first portion of the AC power input is transferred to a first automatic transfer switch (ATS). A first DC power input is generated from the first portion of the AC power input via a first power supply unit (PSU) and transferred to the server rack. A second portion of the AC power input is transferred to a second ATS. A second DC power input is generated from the second portion of the AC power input via a second PSU and transferred to the server rack.
Claims20
A power system for supplying direct current (DC) power to a server rack, the power system comprising:
- a backplane assembly (BPA) configured to be mounted in the server rack and including:
- a BPA DC output electrically connected with DC bus bars of the server rack;
- a BPA first alternating current (AC) input;
- a BPA second AC input;
- BPA automatic transfer switch power supply unit (ATSPSU) connector assemblies, each of the BPA ATSPSU connector assemblies including a BPA first AC output connector electrically coupled with the BPA first AC input, a BPA second AC output connector electrically coupled with the BPA second AC input, and a BPA DC input connector electrically connected with the BPA DC output;
- and
- BPA battery module (BM) connector assemblies, each of the BPA BM connector assemblies including a BM DC connector electrically coupled with the BPA DC output;
- detachably mountable automatic transfer switch power supply units (ATSPSUs), each of the ATSPSUs including:
- a power supply unit (PSU) configured to output DC power;
- an automatic transfer switch (ATS) configured to supply electric power to the PSU and automatically switch between a first AC power source and a second AC power source;
- an ATSPSU controller configured to control operation of the ATS or the PSU;
- and
- an ATSPSU connector assembly configured to electrically connect with one of the BPA ATSPSU connector assemblies, the ATSPSU connector assembly being configured to electrically couple the ATS with each of the BPA first and second AC output connectors and electrically couple the PSU with the BPA DC input connector;
- and
- detachably mountable battery modules, each of the battery modules including:
- a battery cell;
- a battery module (BM) connector assembly detachably and electrically connected with one of the BPA BM connector assemblies;
- and
- a BM controller configured to control DC current flow between the battery cell and the BM connector assembly.
A power system, comprising:
- a backplane assembly (BPA) configured to be mounted in a server rack and electrically coupled with direct current (DC) bus bars of the server rack, a first AC power source, and a second AC power source;
- an automatic transfer switch power supply unit (ATSPSU) configured to be electrically coupled with the DC bus bars, the first AC power source, and the second AC power source via the BPA;
- the ATSPSU including:
- a power supply unit (PSU) configured to output DC power;
- an automatic transfer switch (ATS) configured to supply electric power to the PSU and automatically switch between receiving AC power from a first AC power source and receiving AC power from a second AC power source;
- and
- an ATSPSU controller configured to control operation of the ATS or the PSU;
- a battery module configured to be electrically coupled with the DC bus bars via the BPA and including:
- a battery cell;
- and
- a battery module (BM) controller configured to control DC current flow from the battery cell and the bus bars.
A method, comprising:
- receiving an alternating current (AC) power input from a first AC power source;
- transferring a first portion of the AC power input to a first automatic transfer switch (ATS);
- generating a first DC power input from the first portion of the AC power input via a first power supply unit (PSU);
- transferring the first DC power input to DC bus bars of a server rack;
- transferring a second portion of the AC power input to a second ATS;
- generating a second DC power input from the second portion of the AC power input via a second power supply unit (PSU);
- and
- transferring the second DC power input to the DC bus bars of the server rack.
