Abstract:
1. A two-terminal current controller for controlling a first current passing through a load, wherein: during a rising period of a rectified alternative-current (AC) voltage when a voltage established across the load does not exceed a first voltage, the two-terminal current controller operates in a first mode; during the rising period when the voltage established across the load exceeds the first voltage but does not exceed a second voltage, the two-terminal current controller operates in a second mode; and during the rising period when the voltage established across the load exceeds the second voltage, the two-terminal current controller operates in a third mode; during the rising period when the voltage established across the load drops to a third voltage smaller than the second voltage after exceeding the second voltage, the two-terminal current controller is configured to: the two-terminal current controller includes:
