Abstract
According to some examples, solutions are provided for power distribution of input alternating current (AC) power to at least one power outlet while the input AC power is available, charging of a set of batteries by the input AC power while the input AC power is available, and power distribution of direct current (DC) power from the set of batteries to the power outlet when the input AC power is not available. For such examples, the power outlet is capable of conducting AC power and DC power to a load that is coupled to the power outlet and that can receive either AC power or DC power.
Claims13
A power distribution system, comprising:
- a power inlet to receive input alternating current (AC) power;
- a power outlet to selectively conduct AC power and direct current (DC) power to a load capable of receiving AC power and DC power;
- a set of batteries;
- a power conversion module to convert the input AC power to input DC power;
- a charging module to charge the set of batteries by the input DC power while the input AC power is being received by the power inlet;
- a discharge module to provide output DC power from the set of batteries when the input AC power is not being received by the power inlet;
- and a switching module having a first switch and a second switch, the first switch being enabled and the second switch being disabled to provide the input AC power to the load through the power outlet when the input AC power is being received by the power inlet, and the first switch being disabled and the second switch being enabled to provide the output DC power to the load through the power outlet when the AC power is not being received by the power inlet;
- and a housing including the power inlet, the power outlet, the set of batteries, the charging module, the discharge module, the power conversion module, and the switching module, wherein the housing has a 0 rack unit (U) form factor.
A method, comprising:
- monitoring whether input alternating current (AC) power is being received at a power distribution unit (PDU);
- while the input AC power is being received at the PDU, converting the input AC power to input direct current (DC) power, charging a set of batteries in the PDU by the input DC power, and providing the input AC power to a load capable of receiving AC power and DC power, wherein the input AC power is provided through a power outlet of the PDU;
- and when the PDU is not receiving the input AC power, providing output DC power from the set of batteries to the load by disabling a first switch in a switching module of the PDU and enabling a second switch in the switching module, wherein the output DC power is provided through the power outlet of the PDU;
- wherein the PDU, the set of batteries, the switching module, and the power outlet are included in a housing which has a 0 rack unit (U) form factor.
A non-transitory machine-readable medium having instructions stored thereon, the instructions being executable by a processor of a power distribution unit (PDU), the instructions causing the processor to:
- monitor whether input alternating current (AC) power is being received at the PDU;
- while the input AC power is being received at the PDU, cause the input AC power to be converted to input direct current (DC) power, cause a set of batteries in the PDU to charge by the input DC power, and cause the input AC power to be routed to a load capable of receiving AC power and DC power, wherein the input AC power is routed to the load through a power outlet of the PDU, by enabling a first switch in a switching module of the PDU and disabling a second switch in the switching module;
- and
- in response to the PDU transitioning from receiving the input AC power to not receiving the input AC power, cause output DC power to be routed from the set of batteries to the load, by disabling the first switch and enabling the second switch, wherein the output DC power is routed to the load through the power outlet of the PDU;
- wherein the PDU, the set of batteries, the switching module, and the power outlet are included in a housing which has a 0 rack unit (U) form factor.
