Abstract: An electrical device includes a container, a conversion unit, an outer cover and an inner cover. The container is provided with an inner bottom surface and an inner which define an accommodating channel together. An inlet of the accommodating channel is opposite to the inner bottom surface. The conversion unit is disposed within the accommodating channel. The outer cover covers the inlet of the accommodating channel. The inner cover is disposed within the accommodating channel, and located between the conversion unit and the outer cover. One part of the conversion unit extends to the opening, and at least one outer edge of the inner cover is connected to an inner wall of the container.

Abstract: A cable strain relief structure includes a conducting seat, a cable, a supporting element, and an insulating sleeve. The conducting seat includes an insulating body and a conducting element disposed in the insulating body. The cable passes through the insulating body and is electrically connected to the conducting element. The supporting element includes a plurality of ridges arranged spacedly and annularly on the outer periphery of the cable. The ridges are extended in the direction along the cable and away from the insulating body. The insulating sleeve covers the supporting element and is extended in the direction along the cable.

Abstract: An active bridge rectifying control apparatus includes a bridge rectifying unit and a rectifying control module. The rectifying control module includes a phase control unit, a low-side drive unit, and a self-drive unit. The phase control unit provides a live line signal and a ground line signal according to a positive half cycle and a negative half cycle of an AC power source. The low-side drive unit provides a low-side control signal according to the live line signal and the ground line signal. The self-drive unit establishes a drive voltage according to the positive half cycle and the negative half cycle of the AC power source, and provides a high-side control signal according to the low-side control signal. The bridge rectifying unit rectifies the AC power source into a DC power source according to the low-side control signal, the high-side control signal, and the drive voltage.
