Power adapter manufacturers: switching power adapter insulation cover need to pay attention to what issues?

Power supply engineers in the switching power adapter new product development process, not only need to take into account the full range of product packaging, circuit design, thermal design and anti-electromagnetic interference and other issues, insulation cover design is also a very important part of the design. Next power adapter manufacturers will briefly analyze the insulation cover design to help engineers fully understand the insulation cover design points of the adapter.

Adapter in the process of operation, sometimes there will be circuit surge suddenly higher than the risk of voltage, in order to protect the normal operation of the circuit, it is necessary to take appropriate insulation cover technology. Usually, the more common insulation cover technology is generally divided into the following types:

First let's look at the additional insulation technology. The so-called additional insulation technology, is independently added to the basic insulation, can guarantee in the basic insulation occasionally effective, supply to the electric shock of the second level of cover. However, it should be noted that the minimum thickness of the additional insulation single layer material must be greater than or equal to 0.4mm, so as to effectively provide cover protection.

The second more common insulation technology is to strengthen the insulation technology. This technique is one of the many insulation systems used to avoid electrocution, and it is functionally equivalent to double insulation. When using the reinforced insulation technique for circuit design, the minimum thickness of the single layer used inside is greater than or equal to 0.4mm, which enables several layers of insulation to be safeguarded, but each layer cannot be tested alone.

The third common insulation method is base insulation. This technology is to avoid the switching power adapter was electrocuted by the most basic insulation method, but also at present all kinds of textbooks introduced in the more clear insulation technology, this paper does not go into too much detail here. However, the basic insulation alone is not absolutely safe, engineers also need to reach the safety requirements through additional insulation and cover grounding secondary cover, such as coil interlayer insulation.

These are power adapter manufacturers for switching power adapter insulation cover the problem and a brief summary and analysis, I hope to help engineers in the process of new product development more comprehensive insulation design, develop better power products.
