Power supply system and container data center including same

A power supply system to provide a voltage for a container data center, the power supply system comprising:

• at least one solar energy panel, to receive solar energy and output a direct current (DC) voltage;
• a power measuring unit connected to the at least one solar energy panel, to compare the received DC voltage from the at least one solar energy panel with a reference voltage preset in the power measuring unit, thereby to determine whether there is enough energy generated by the solar energy panel to power the container data center;
• a switch unit connected to the power measuring unit, wherein the power measuring unit outputs a first control signal to control the switch unit to be in a first work state or outputs a second control signal to control the switch unit to be in a second work state according to a compared result of the power measuring unit;
• an uninterrupted power supply (UPS) connected between a power distribution device of the container data center and the switch unit;
• and
• a direct current to alternating current (DC/AC) voltage converting unit connected between the power distribution device and the switch unit, to convert the received DC voltage to an AC voltage and output the converted AC voltage to the power distribution device;
• wherein when the received DC voltage is greater than or equal to the reference voltage, the power measuring unit outputs the first control signal to control the switch unit to be in the first work state and outputs the received DC voltage to the DC/AC voltage converting unit through the switch unit;
• wherein when the received DC voltage is less than the reference voltage, the power measuring unit outputs the second control signal to control the switch unit to be in the second work state and outputs the received DC voltage to the UPS through the switch unit;
• and
• wherein the power distribution device receives the AC voltage from the DC/AC voltage converting unit and outputs the received AC voltage to the container data center, wherein the power distribution device receives the AC voltage from the UPS and outputs the received AC voltage to the container data center when the power distribution device does not receive the AC voltage from the DC/AC voltage converting unit.

A container data center comprising:

• a power distribution device;
• a portable container;
• and
• a power supply system comprising:
• at least one solar energy panel positioned on the container, to receive solar energy and output a direct current (DC) voltage;
• and
• a direct current to alternating current (DC/AC) voltage converting unit connected to the at least one solar energy panel, to receive the DC voltage and convert the received DC voltage to an AC voltage, and outputs the converted AC voltage to the power distribution device.
