Title:
POWER SUPPLY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/007558
Kind Code:
A1
Abstract:
This power supply apparatus (1) comprises a bypass circuit (11), an energization circuit (12), and an abnormality determination unit (22). The bypass circuit (11) is disposed parallel to a first switching element (10), has a resistive part (11A), and has electric current flowing from a power supply unit (90) side to a load (91) side through the resistive part (11A). The energization circuit (12) is disposed between a first electrical conduction path (81), which is situated between the load (91) and the bypass circuit (11) in an electric power path (80), and a second electrical conduction path (82) which is the ground, and is configured to allow electric current to flow from the first electrical conduction path (81) to the second electrical conduction path (82) in an energized state. The abnormality determination unit (22) determines an abnormality on the basis of a voltage drop in the resistive part (11A) while the energization circuit (12) is in an energized state.
