摘要： A two-terminal current controller regulates a first current flowing through a load, which is coupled in parallel with the two-terminal current controller, according to a voltage established across the two-terminal current controller. When the voltage established across the two-terminal current controller does not exceed a first voltage, the two-terminal current controller conducts a second current related to a rectified AC voltage, thereby limiting the first current to zero and regulating the second current according to the load voltage. When the voltage established across the two-terminal current controller is between the first voltage and a second voltage, the two-terminal current controller conducts the second current, thereby limiting the first current to zero and limiting the second current to a constant value larger than zero. When the voltage established across the two-terminal current controller is greater than second voltage, the two-terminal current controller is turned off.

摘要： A two-terminal current controller controls a first current flowing through a parallel-coupled load. During a rising period of a rectified AC voltage, when a load voltage does not exceed a first voltage, the two-terminal current controller operates in a first mode. When the load voltage exceeds the first voltage but does not exceed a second voltage, the two-terminal current controller operates in a second mode. When the load voltage exceeds the second voltage, the two-terminal current controller operates in a third mode. When the load voltage drops to a third voltage smaller than the second voltage after exceeding the second voltage, the two-terminal current controller operates in the second mode when a difference between the second and third voltages exceeds a hysteresis band and operates in the third mode when a difference between the second and third voltages does not exceed the hysteresis band.

摘要： A two-terminal current controller having a current limiting unit and an adjusting unit regulates a first current flowing through a load according to a load voltage. When the load voltage does not exceed a first voltage, the two-terminal current controller operates in a first mode for conducting a second current associated a rectified AC voltage, thereby limiting the first current to zero and adjusting the second current accordingly. When the load voltage is between the first voltage and a second voltage, the two-terminal current controller operates in a second mode for conducting the second current, thereby limiting the first current to zero and limiting the second current to a constant value larger than zero. When the load voltage exceeds the second voltage, the two-terminal current controller operates in a third mode for turning off the current limiting unit. The adjusting unit can adjust the predetermined value and the second voltage.

摘要： A power converter includes an inductor, first through fourth switches, and a control device. The first switch is coupled between a first end of the inductor and ground, the second switch is coupled between an input end and a second end of the inductor, the third switch is coupled between the first end of the inductor and a first output end, and the fourth switch is coupled between the second end of the inductor and a second output end. The control device charges the inductor by turning on the first and second switches. Based on output voltages of the first and second output ends, the control device determines whether the first and second output ends are to be charged or discharged. The second and third switches are turned on for charging the first output end, or the first and fourth switches are turned on for discharging the second output end.
