Abstract
A solid state power controller configured to supply electric power from a power supply to at least one load, comprises: a solid state switching device having a first terminal (D) connected to the power supply, and a second terminal (S) connected to the load, the solid state switching device configured to switch between an OFF operation mode in which the second terminal (S) is electrically disconnected from the power supply, and an ON operation mode in which the second terminal (S) is electrically connected to the power supply, and a load current detection unit configured to detect a load current through the solid state switching device; wherein the load current detection unit comprises a first load current amplifier and a second load current amplifier.

A solid state power controller configured to supply electric power from a power supply to at least one load, comprising:
- a solid state switching device having a first terminal (D) connected to the power supply, and a second terminal (S) connected to the load, the solid state switching device configured to switch between an OFF operation mode in which the second terminal (S) is electrically disconnected from the power supply, and an ON operation mode in which the second terminal (S) is electrically connected to the power supply, and
- a load current detection unit configured to detect a load current through the solid state switching device;
- wherein the load current detection unit comprises a first load current amplifier and a second load current amplifier, the first load current amplifier providing a first load current output signal having a first bandwidth and the second load current amplifier providing a second load current output signal having a second bandwidth.
