Title:
電源装置およびこの電源装置を備えたモータ制御装置
Document Type and Number:
Japanese Patent JP7291873
Kind Code:
B2
Abstract:
A power device includes: a DC voltage output circuit that generates a DC internal power voltage from external supply power; a capacitor that is connected to the internal power voltage; and a voltage supply control circuit that monitors a voltage level of the internal power voltage and that, when detecting a drop in the internal power voltage, cuts off supply of the internal power voltage. The power device supplies internal power to a load. The power device supplies, to a first load that is a part of the load, the internal power voltage, and supplies, to a second load that is a load other than the first load, the internal power voltage via the voltage supply control circuit.
