Abstract
A wireless communication system base station (20) includes a base station transceiver (26) that has at least one operative component (32) for facilitating wireless communications. A current limiting device (36) includes at least one field effect transistor for selectively controlling current flow to a capacitive stability device (34) associated with at least one of the operative components (32). In the disclosed example, the current limiting device (36) is in series with the capacitive stability device (34) but in parallel with the operative component (32).
Claims19
A device for limiting a current through an operative component powered by a power supply, comprising:
- a capacitive stability device coupled in parallel with the at least one operative component;
- and
- a current limiting device coupled in series with the capacitive stability device between the power supply and the capacitive stability device, and coupled in parallel with the operative component;
- wherein the current limiting device is configured to operate in an initial state to restrain a charging current to the capacitive stability device, and further configured to operate in a steady state to allow the charging current to flow to the capacitive stability device.
A method of controlling power supply to an operative component, comprising:
- providing a current limiting device in series with a capacitive stability device, between the power supply and the capacitive stability device, and in parallel with the operative component;
- operating the current limiting device in an initial state where the current limiting device restrains a charging current to the capacitive stability device, and without passing a steady state power supply to the operative component;
- and
- operating the current limiting device in a steady state to allow the charging current to flow to the capacitive stability device.
