Abstract
A current integrating circuit device, including a current sensor to detect a current flowing through a current path, a first-order lag filter to filter an output of the current sensor, an A/D converter to convert an analog signal filtered by the first-order lag filter into a digital signal, and a proportional integrator to proportionally integrate the digital signal outputted from the A/D converter.
Claims17
A current integrating circuit device, comprising:
- a current sensor to detect a current flowing through a current path;
