Charging device, system, and method of supplying power to at least one load

A system for supplying power to at least one load, said system comprising:

• a power measurement device configured to measure at least one characteristic of electricity transmitted within an electrical distribution bus;
• a charging device coupled to said power measurement device, said charging device comprising:
• a power conditioning device configured to be coupled to a three phase electric power source by the electrical distribution bus, said power conditioning device further configured to receive alternating current (AC) volt-amperes from the three phase electric power source, said power conditioning device having a volt-amperes capacity;
• and
• a controller coupled to said power conditioning device, said controller configured to:
• determine, using a d-q-n transformation, a first amount of the volt-amperes capacity to be converted to direct current (DC) power by said power conditioning device;
• control said power conditioning device to convert the first amount of the volt-amperes capacity to DC power and to supply the DC power to at least one load when the first amount is greater than zero;
• determine, using a d-q-n transformation, a second amount of the volt-amperes capacity, wherein the second amount is a difference between the volt-amperes capacity and the first amount;
• and
• control said power conditioning device to supply volt-amperes reactive to the electrical distribution bus using at least a portion of the second amount of the volt-amperes capacity when the second amount is greater than zero.

A method of supplying power to at least one load, said method comprising:

• receiving alternating current (AC) volt-amperes from a three phase electric power source through an electrical distribution bus;
• determining, using a d-q-n transformation, a first amount of the AC volt-amperes to be supplied to at least one load;
• converting the first amount of the AC volt-amperes received into direct current (DC) power when the first amount is greater than zero;
• supplying the DC power to the at least one load when the first amount is greater than zero;
• determining, using a d-q-n transformation, a second amount of volt-amperes, wherein the second amount is a difference between a maximum volt-amperes capacity and the first amount;
• and
• supplying volt-amperes reactive to the electrical distribution bus using at least a portion of the second amount of volt-amperes when the second amount of volt-amperes is greater than zero.
