Title:
LOAD CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022029794
Kind Code:
A
Abstract:
To suppress operation of a load from becoming unstable when switching from a power supply state where power is supplied to the load to a cut-off state where the power supply to the load is cut off.SOLUTION: A first power supply unit 13 includes a DC/DC converter 132 connected between a pair of connection terminals TA1 and TA2 and a power storage unit C1, and charges the power storage unit C1 by applying an output voltage of the DC/DC converter 132 to the power storage unit C1 in a cut-off state where power supply from an AC power source 2 to a load 3 is cut off. A second power supply unit 14 charges the first power supply unit 13 by forming a changing path of lower impedance in relative to the first power supply unit 13 between the pair of connection terminals TA1 and TA2 and the power storage unit C1 in a power supply state where power is supplied from the AC power source 2 to the load 3.SELECTED DRAWING: Figure 1
