Title:
DC STABILIZING POWER SOURCE SYSTEM
Document Type and Number:
Japanese Patent JP2017005944
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a DC stabilizing power source system that restricts large-sizing of a power source or the like in a DC-main electric system and that is able to absorb electric power fluctuation satisfactorily.SOLUTION: A first DC power source part 12A comprises at least a dynamo 42 and a PWM converter 20, and a second DC power source part 13A comprises at least a battery 43 and a boosting converter 30. These DC power source parts 12A, 13A perform a power supply stabilization operation for supplying DC electric power to an electric system and absorbing regenerative electric power generated by an actuator 15 and so on. Additionally, the PWM converter 20 alters a voltage target value for a DC bus 14, thereby controlling the adjustment of assigned amount of power supply stabilization operation performed by each of the two DC power supply parts 12A, 13A.SELECTED DRAWING: Figure 1
