Description

Technical Field

[0001] The utility model relates to the technical field of inverters, in particular to an inverter inductor. Background Art

[0002] Inverter inductors play a vital role in inverters. Inductors, also known as chokes or reactors, are components that can convert electrical energy into magnetic energy and store it. Its structure is similar to that of a transformer, but it has only one winding. Inductors in inverters have multiple functions, including energy storage, voltage boosting, filtering, and eliminating electromagnetic interference (EMI). At the output end of the inverter power supply, inductors are often used for filtering. The filtering effect can reduce high-frequency noise interference, stabilize the output voltage, and extend the service life of the capacitor, thereby ensuring the normal operation of the inverter power supply. In addition, inductors can balance the current in the circuit by storing and releasing energy, making the output voltage more stable and playing a role in voltage stabilization. During the operation of the inverter, inductors are also responsible for transmitting energy. When the electronic switching device is turned on and off, the inductor stores energy; and when the on-off state of the switching device changes, the inductor releases energy. By controlling the energy storage and release of the inductor, the inverter can achieve precise control and regulation of the current. For different types of inverters, the application of inductors is also different. In single-phase inverters, inductors are mainly used for filtering and voltage stabilization to ensure output voltage stability and smaller ripples. In three-phase inverters, the role of inductors is more complex. In addition to filtering and voltage stabilization, they are also used to achieve three-phase current balance and regulation.

It is easy to be damaged when encountering external force collision, resulting in the inverter being unable to be used normally, affecting the quality of use of the inverter. Therefore, an inverter inductor is proposed to solve the above problem. Utility Model Content
