The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] The utility model provides a portable inverter. In a specific embodiment, the inverter includes a shell 100. A cavity for accommodating electronic components is arranged in the shell 100. The cavity is divided into a first area 111 and a second area 112. An inductor module 210 and a capacitor module 220 are arranged in the second area 112, and the capacitor module 220 is arranged horizontally. A PCB board 230 is arranged in the first area 111, and the PCB board 230 is electrically connected to the inductor module 210 and the capacitor module 220.

[0022] In this embodiment, the shell cavity is divided into a first area 111 and a second area 112 in parallel by a partition or other existing methods, wherein the first area 111 is used to accommodate the circuit board, and the second area 112 is used to accommodate the inductor module 210 and the capacitor module 220; further, the second area 112 can also be divided into a first accommodating cavity 1121 and a second accommodating cavity 1122 in parallel by a partition or other existing technical methods; wherein the first accommodating cavity 1121 is used to install the inductor module 210, and the second accommodating cavity 1122 is used to install the capacitor module 220; on the one hand, it is easy to install, and on the other hand, the partition or other partitioning components can be used to reduce the electromagnetic interference between the two chambers, thereby further improving the stability of the inverter in AC-DC conversion.

[0023] In this embodiment, the capacitor module 220 includes a capacitor body, which is arranged horizontally in the second accommodating cavity 1122, resulting in a significant reduction in the height direction of the entire inverter, which further results in a reduction in its overall volume, especially for high-power inverters, the volume of the inverter can be reduced by more than 15% relative to the prior art; secondly, the utility model adopts a modular layout, which can further improve the equipment efficiency and the efficiency of replacing parts.

[0024] In other embodiments, reference Figure 1-3 , the PCB board 230 is provided with an inductor connecting part 231, which is arranged at the edge of the PCB board 230 and its position corresponds to the inductor module 210; in addition, the PCB board 230 is provided with a capacitor connecting part 232, which is also arranged at the edge of the PCB board 230 and its position corresponds to the capacitor module 220. The capacitor module 220 includes a capacitor body 221 and an electrical adapter plate 222 connected to each other, and the other end of the electrical adapter plate 222 is connected to the PCB board 230.

[0025] In other embodiments, the housing has a stepped structure, that is, the housing 110 corresponding to the first area 111 and the second area 112 is arranged in a stepped manner. From the side of the housing 110, the housing 110 has a stepped structure, that is, the second area 112 is higher in height than the first area 111. On the one hand, it is convenient to accommodate larger electronic components in the second area 112, and on the other hand, the volume of the inverter is reduced compared to the whole. At the same time, the stepped structure has a larger heat dissipation area and better heat dissipation effect than before, which further improves the heat dissipation efficiency of the inverter.
