From the research and development to the production of a switching power adapter, engineers must consider numerous factors, such as product packaging, circuit design, thermal management, as well as aesthetics, size, and a host of other issues. As mentioned in the question,
Switching power adapter Insulation protection is also a very important factor.
In general, the three most common insulation‑protection techniques are: first, reinforced insulation; second, supplementary insulation; and third, basic insulation. Under what circumstances is insulation‑protection technology employed? Typically, during operation, switch-mode power adapters may occasionally experience transient overvoltages within the circuit. To ensure the proper functioning of the power supply, it is essential to implement insulation‑protection measures.
First, let’s examine the first point: reinforcing insulation technology. This approach is quite common and provides an effect comparable to double insulation. When designing circuits using this method, it is optimal to ensure that the minimum thickness of each individual insulating layer is 0.4 mm or greater, thereby offering multiple layers of insulation protection. Moreover, this technique is one of several insulation systems employed to prevent electric shock.
Second, let’s discuss supplementary insulation technology. With this approach, it is crucial to ensure that the minimum thickness of a single layer of supplementary insulation is at least 0.4 mm; only then can it be truly effective. The principle behind this technique is that the supplementary insulation is applied independently on top of the basic insulation, but it functions only intermittently, providing secondary protection against electrical breakdowns.
The third insulation‑protection method is basic insulation. This approach is very common and represents the most fundamental way to address electric shock in switch-mode power adapters; we will not go into further detail here. However, it is not absolutely safe, so engineers must pay close attention to certain considerations when employing this method.
