Abstract: A choke coil module of a high power density DC-AC power inverter includes a bottom plate and a top plate. Two upright posts are secured between the bottom plate and the top plate. The upright posts are sleeved with choke coils, respectively. The choke coils and heat radiating holes of the bottom plate and the top plate are communicated with one another to form an air guide passage. When the power converter is actuated, the choke coils generate heat. Through a fan unit, the outside air is guided into a casing via air inlets of the casing, and the heat generated by the choke coils is expelled to the outside via the air guide passage and air outlets of the casing. The choke coil module mounted in the high power density casing is able to achieve an excellent heat radiation effect.

Abstract: An improved structure of a power input end and a power output end of a power supply device is provided. The power supply includes a casing and a main body. A rear side of the casing is provided with a back plate having first heat dissipation holes. One side of an inner wall of the casing is provided with a power input end and a protection cover. A rear side of the protection cover is provided with an upright plate having a threaded hole and second heat dissipation holes parallel to the first heat dissipation holes. The interior of the casing is provided with two power output ends each in the form of a plate perpendicular to the back plate. The present invention lowers the sheltered area of the back plate to form a better heat dissipation structure. The protection cover can be disassembled easily.

Abstract: A power transmission structure of a power supply unit includes a base plate. The base plate is provided with a plurality of spaced metallic plates. One end of each metallic plate is provided with a first connecting portion and the other end is provided with a second connecting portion to connect the components of the power supply unit respectively for power transmission. Thus, the present invention can take the place of conventional power cords, and the power transmission structure can be flattened to decrease the space occupied by the power transmission device, such that the required interior accommodation space of the power supply unit can be decreased effectively and the volume of the power supply unit can be reduced.

Abstract: A synchronizing circuitry for AC-DC switch mode power supplies includes a master control circuit connected to one or more slave control circuits through one or more communication interfaces. With the communication interfaces, the master control circuit and the slave control circuits can be connected using existing communication loops, so that when the master control circuit performs master-slave control on the slave control circuits, the slave control circuits have synchronous connection with the master control circuit, thereby mitigating electromagnetic interference that may happen during master-slave control, and effectively reducing noise. As a result, signal transmission is more efficient and master-slave control is more responsive.
