Abstract
A power source system including power-factor modifying circuits to modify a power factor of supplied electric power, a time difference circuit to output start signals for instructing the power-factor modifying circuits to start an operation to the power-factor modifying circuits at specified time intervals, and a control circuit to supply the electric power to the power-factor modifying circuit to start the power-factor modifying circuit when the power-factor modifying circuit acquires the start signal output from the time difference circuit.
Claims8
A power source system comprising:
- power-factor modifying circuits to modify a power factor of supplied electric power;
- and
- a time difference circuit to output start signals for instructing the power-factor modifying circuits to start an operation to the power-factor modifying circuits at specified time intervals,
- wherein the power-factor modifying circuits respectively include a switch, and
- each switch receives the electric power for the power-factor modifying circuit to start the power-factor modifying circuit when each switch turns on based on the start signals output from the time difference circuit, and continuously passes the electric power to the power-factor modifying circuits while the power-factor modifying circuits are operating after starting to supply the electric power to the power-factor modifying circuits.
A power source control circuit comprising:
- power-factor modifying circuits modifying a power factor of supplied electric power;
- a time difference circuit to output start signals for instructing the power-factor modifying circuits to start an operation to the power-factor modifying circuits at specified time intervals;
- and
- a switch to receive the electric power for a power-factor modifying circuit to start the power-factor modifying circuit when the switch turns on based on the start signals output from the time difference circuit,
- wherein the switch is included in the power-factor modifying circuits, and continuously passes the supplied electric power to the power-factor modifying circuit while the power-factor modifying circuit is operating after starting to supply the electric power to the power-factor modifying circuit.
