Power supply

Frequency converters provide power and control for commercial and industrial motors and must be thermally protected according to their design and application environment. The main advantages of the fr

Wireless charging technology breaks the traditional connection line charging. It is a wireless charging technology using intelligent power transmission. It not only improves the efficiency and conveni

With the reduction of the overall size of photovoltaic inverter and the improvement of single machine power, the requirements for thermal design are higher and higher. The designer must comprehensivel

The power supply module has energy loss in the process of voltage conversion. The generation of thermal energy leads to the heating of the module, reduces the conversion efficiency of the power supply

During the operation of the power module, because the power consumption will occur inside the module and will be generated in the form of heat, if these heat are not radiated, it will accumulate insid

If the power of IGBT module is constant and the thermal resistance between IGBT shells is constant, the thermal resistance between IGBT shell and hetasink is related to the material and contact degree

As a conversion device, motor frequency converter will produce certain power consumption during operation. This part of power consumption will vary according to different loads, different control mode

MOS tubes, diodes, transformers and other spare parts in the power module will generate large heat during operation, and the continuous high temperature will have a great impact on its reliability, su

The efficiency of theinverter is generally 97 ~ 98%, which means that about 2 ~ 3% of the electric energy is transformed into heat energy, which is much greater than the heat generated by general swit

IGBT is the core device of energy conversion and transmission, commonly known as the "CPU" of power electronic devices. As a national strategic emerging industry, IGBT is widely used in the

The causes of UPS overheating and how to solve the heat dissipation problem of ups. At present, with the continuous acceleration of modernization process, various infrastructures are becoming more and

Modern power electronic equipment is rapidly developing towards high integration, high-density assembly and high operation speed. As the core of power electronic equipment, the chip works faster and f
