Abstract
In a power supply system connected to a load, a plurality of DC power source units are connected in parallel. Each DC power source unit is provided with a unit rated current value Iu, and outputs a unit current in accordance with a target value. A required load capacity provider provides a capacity value Is required in the load. An operating condition detector detects the number m of DC power supply unit which is in an operating condition among the DC power source units. A target value calculator calculates a value obtained by dividing the value Is with the value m, and provides the calculated value Is/m to the respective operating DC power supply unit as the target value.
Claims5
A power supply system connected to a load, comprising:
- a DC power supplier, in which a plurality of DC power source units are connected in parallel, each DC power source unit provided with a unit rated current value Iu, and outputting a unit current in accordance with a target value;
- a required load capacity provider, which provides a capacity value Is required in the load;
- an operating condition detector, which detects the number m of DC power supply unit which is in an operating condition among the DC power source units;
- and
- a target value calculator, which calculates a value obtained by dividing the value Is with the value m and provides the calculated value Is/m to the respective operating DC power supply unit as the target value.
A method of controlling an electric power supplied from a power supply system to a load, comprising the steps of:
- providing a capacity value Is required in the load;
- detecting the number m of DC power supply unit which is in an operating condition among a plurality of DC power supply units connected to the load in parallel;
- calculating a value obtained by dividing the value Is with the value m;
- providing the calculated value Is/m to the respective operating DC power supply unit as a target value;
- and
- adjusting a unit current outputted from each operating DC power supply unit so as to be coincident with the target value.
