摘要： A solid state power controller, SSPC, having an input to receive supply current and an output for providing output current to a load in response to connection to the power supply, the solid state power controller further comprising at least one solid state switch and a controller to limit the power dissipated in the solid state power switch based on a measured voltage across the solid state switch and a predetermined power dissipation threshold for the SSPC to adjust the output current or voltage control signal of the solid state switch such that the actual power dissipation of the SSPC does not exceed the threshold.
