Title:
直流安定化電源システム
Document Type and Number:
Japanese Patent JP6502758
Kind Code:
B2
Abstract:
A first DC power supply section (12A) of a DC stabilization power supply system includes at least a generator (42) and a PWM converter (20). A second DC power supply section (13A) of the DC stabilization power supply system includes at least a battery (43) and a boost converter (30). Each of these DC power supply sections (12A, 13A) performs a power supply stabilization operation for supplying DC power to an electric system and absorbing regenerative power generated from an actuator (15) or the like. A PWM converter (20) controls adjustment of the amount of the power supply stabilization operation to be performed by the DC power supply section (12A) and the amount of the power stabilization operation to be performed by the DC power supply section (13A), by changing a target voltage value of a DC bus (14).
