The application discloses a packaging structure of a power module, which comprises an insulating substrate, a plurality of base islands, a power device, a first diode, a second diode, a signal terminal, a power terminal and a plastic package body. The combination of the power device and the first diode is packaged together with the second diode, so that the stray inductance in the device is reduced, the layout and wiring are simplified, the device performance is improved, the application range of the device is wider, and the space utilization is greatly improved.

This application relates to the field of power converter technology, specifically to a power module and a power converter. This application aims to solve the technical problem of excessive parasitic inductance introduced into the circuit board, leading to significant power loss in the power converter. Embodiments of this application provide a power module, including a package, a first power chip, and a second power chip. Both the first and second power chips are packaged within the package. The power module also includes connecting lines disposed within the package. The first and second power chips are electrically connected via these connecting lines, facilitating the integration of the power module and improving the power density of the power converter. Because the connecting lines are disposed within the package, and the first and second power chips are electrically connected via these connecting lines, the trace distance on the circuit board can be reduced, lowering the parasitic inductance on the circuit board and thus reducing the power loss of the power converter.

The application discloses an isolation assembly and an energy storage device, relates to the technical field of energy storage devices, and comprises a first protective piece, wherein the first protective piece comprises a first protective part, and the first protective part is made of insulating material. The first protective part comprises a plurality of isolation plates arranged at intervals, and each isolation plate is arranged between two adjacent wiring branches to insulate and isolate the exposed live parts of the plurality of wiring branches arranged side by side and at intervals, in particular the exposed live parts of the wiring branches, and to reduce the diffusion of circuit arc discharge between adjacent wiring branches, so that the safety hazard can be reduced and the loss can be reduced. The isolation assembly disclosed by the application prolongs the electrical gap by the second protective part with insulation performance, realizes the insulation isolation between the exposed live parts of each wiring branch arranged side by side, suppresses the diffusion of the single wiring branch circuit arc discharge phenomenon, reduces the safety hazard, and improves the safety protection performance.

The application provides a hanging adjustable phase type fuse type isolating switch, which comprises a switch body, a conductive busbar and a busbar clamp assembly arranged on the switch body, the busbar clamp assembly is movable along the length direction of the conductive busbar and is suitable for clamping an incoming line busbar, the busbar clamp assembly is arranged to be flexible in position, so that a user can freely take power according to own needs, and the production cost is greatly reduced.
