Title:
CURRENT-LIMITING DRIVER CIRCUIT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/063120
Kind Code:
A1
Abstract:
A driver circuit comprising an input inductor for receiving an input current provided to the driver circuit, and one or more switchable capacitors. Each switchable capacitor is switchable to connect in parallel across the input inductor and to disconnect from the input inductor, the input inductor and the switchable capacitors together thereby providing a variable impedance corresponding to the number of switchable capacitors are switched to connect to the input inductor, with the variable impedance variably limiting the input current. An associated method and an associated system are also provided.
