Title:
RMS DETECTOR AND CIRCUIT BREAKER USING THE SAME
Document Type and Number:
Japanese Patent JP2014157155
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an RMS detector for directly computing a signal detected through an analog circuit to measure its RMS value, and a circuit breaker using the same.SOLUTION: An RMS detector according to the present invention includes: a plurality of voltage/current sensing units 100 configured to detect a voltage or current shaped analog signal for an arbitrary load; a plurality of square circuit units 200 configured to compute square functions, respectively, based on a voltage output from the plurality of voltage/current sensing units 100; a summing circuit unit 300 configured to sum a plurality of output voltages output from the plurality of square circuit units 200, respectively; and a root circuit unit 400 configured to compute an RMS value based on a voltage output from the summing circuit unit 300.
