Current measurement circuit comprising a mutually coupled transformer and an integration circuit. |
摘要 |
<p>A current measurement circuit comprising a mutual inductance transformer (3), an integration circuit (2), and a dither circuit (1) which adds a square wave to the signal from the transformer (3) before the input of the integration circuit (2) in order that the integration circuit (2) provides a signal representing the measured current perturbed by a triangular dither signal. <IMAGE></p> |
