スイッチング電源装置およびそれを利用したモータ駆動制御システム
Document Type and Number:
Japanese Patent JP7231206
Kind Code:
B2
Abstract:
To avoid a configuration for directly interrupting a line of a drive power supply and to secure a power supply for control for a control system even if supply of power for power (drive) is interrupted.SOLUTION: A switching power supply device is constituted of: a power supply circuit; a power interruption circuit; and a control power supply circuit. The power supply circuit comprises: a switching element for a power supply which switches DC input; a smoothing circuit for the power supply which is provided on an output side of the switching element for the power supply to output the power supply; and a switching control circuit for the power supply which controls the switching element for the power supply. The power interruption circuit turns the switching element for the power supply off to stop output of the power supply in response to a given power interruption command signal. The control power supply circuit continues outputting the control power supply irrespective of presence/absence of the power interruption command signal.SELECTED DRAWING: Figure 1
