    摘要： A power supply for illumination includes a detection circuit and a control circuit. The detection circuit compares an AC voltage whose phase is controlled with a first threshold voltage so as to detect a variation in a conduction state of phase control in the AC voltage, and compares the AC voltage with a second threshold voltage lower than the first threshold voltage so as to detect a zero-cross point of the AC voltage, thereby detecting a conduction period of the phase control. The control circuit outputs an output current according to the duration of the conduction period.

    摘要： According to one embodiment, a control section receives supply of control power from a control power supply section through a capacitive element and divides, a period of each half cycle of an alternating-current voltage into a first section, a second section, and a third section. In the first section, the control section subjects a switch section to conduction control to supply electric power to a load and stops a converting action of the control power supply section. In the second section, the control section subjects the switch section to non-conduction control to interrupt the power supply to the load and stops the converting action of the control power supply section. In the third section, the control section subjects the switch section to the non-conduction control to interrupt the power supply to the load and causes the converting action of the control power supply to operate.

    摘要： Disclosed is an interface circuit including a rectifier circuit, a detection circuit, a first circuit, and a second circuit. The rectifier circuit rectifies an AC voltage input between a pair of input terminals. The detection circuit detects the AC voltage and outputs the result as a detection voltage. The first circuit is controlled to be turned on or off on the basis of an input first control signal, to cause a first current to flow between the input terminals in an on state and to cut off the first current in an off state. The second circuit is controlled to be turned on or off on the basis of an input second control signal, to allow a second current greater than the first current to flow between the input terminals in an on state and to cut off the second current in an off state.

    摘要： According to one embodiment of a DC power supply feeding system, the system includes a DC voltage power supply that outputs a specified voltage by using a commercial AC power supply, a varying voltage power supply that generates power by using natural energy and outputs a varying voltage, and a reverse flow preventing elements that connects the DC voltage power supply and the varying voltage power supply in parallel while output sides are made to have same polarity, and supplies powers obtained from the DC voltage power supply and the varying voltage power supply to a load. When an amount of power generation of the varying voltage power supply is small, the power is intermittently supplied to the load.
