Abstract: This power transmission device is connected between an AC wiring system connected to an AC power supply, and a DC power supply, and transmits power from the DC power supply to the AC wiring system. The power transmission device includes an AC power supply voltage signal generator, a power converter, a DC voltage conversion unit, a switching element, and a switch open/close signal generator. The switch open/close signal generator includes: a control signal generation unit to generate a control signal formed from a pulse signal; and a pulse width determination unit to receive the control signal and generate a delayed signal obtained by delaying rising of the control signal, and when the delayed signal becomes a value corresponding to a magnitude of voltage of the AC power supply voltage signal, cause the control signal to fall, thereby making the control signal into the switch open/close signal.

Abstract: The present invention provides a magnetic core having insulating properties, and a method for manufacturing the magnetic core. Provided is a magnetic core manufactured by compression molding and subsequent thermal curing of an iron-based soft magnetic powder having a resin coating formed on particle surfaces thereof. The iron-based soft magnetic powder is one in which the particle surfaces have been coated with an inorganic insulator; the resin coating is an uncured resin coating formed by dry blending the powder with a thermosetting resin at a temperature equal to or greater than the softening point of the thermosetting resin and lower than the thermal curing initiation temperature of the resin; the compression molding is carried out by using a mold to produce a compression molded body; and the thermal curing is carried out at a temperature equal to or greater than the thermal curing initiation temperature of the thermosetting resin.

Abstract: The present invention provides a magnetic core part by which failures such as cracks do not occur even if the magnetic core part contains 90% by mass or more of an amorphous metal powder. The magnetic core part is formed by thermoset molding at least one magnetic powder selected from an amorphous metal powder alone and an amorphous metal powder coated with an insulating material, and a thermosetting binder resin. The magnetic core part contains the magnetic powder in an amount of 90% by mass or more and 99% by mass or less with respect to the total amount of the magnetic powder and the thermosetting binder resin.

Abstract: A charging device includes a rectifier circuit that rectifies an alternating current of an AC power supply, and outputs the rectified alternating current as a pulsating current; power factor correction unit that enhances a power factor of the pulsating current outputted from the rectifier circuit; and an output circuit. The output circuit has an output terminal connecting to a charging terminal of a charging target device, and outputs a power-factor-corrected pulsating current outputted from the power factor correction unit, without performing voltage smoothing. The charging device further includes charging level detection unit that monitors a terminal voltage of a battery of the charging target device, and detects a charging level of the battery based on a fluctuating range of a ripple voltage, in the terminal voltage, generated by the pulsating current.
