Document Type and Number:
WIPO Patent Application WO/2024/075267
Kind Code:
A1
Abstract:
A noise filter (100) according to the present disclosure is provided to either a cable run (2) connecting an AC or DC power source (1) and a power conversion device (80) that converts power outputted from the power source (1) into AC or DC power or a cable run (11) connecting the power conversion device (80) and a load. The noise filter comprises: a noise detection unit (12) that detects common-mode noise generated during the operation of the power conversion device (80); a cancellation signal generation unit (16) that generates a cancellation signal which cancels the common-mode noise; a cancellation signal injection unit (14) that injects the cancellation signal into the cable run (2, 11); and an abnormality detection unit (17) that outputs an abnormality detection signal when the cancellation signal is detected to be abnormal. The noise filter (100) executes an abnormality processing sequence on the basis of the abnormality detection signal.
