(1) High power; Modern consumer electronics products with high efficiency have increasingly higher requirements on volume, which must require customized power modules to reduce volume and develop power density, and continuous improvement of efficiency is complementary to them.
In the early 1980s, the research on the distributed high frequency switching power supply system basically focused on the research of the converter parallel technology. In the mid-to-late 1980s, with the rapid development of high-frequency power conversion technology, various converter topologies appeared one after another. Combined with large-scale integrated circuit and power component technology, it became possible to integrate small and medium power devices, thereby rapidly Promote the development of distributed high-frequency switching power supply system research. Since the late 1980s, this direction has become a research hotspot in the international power electronics field.
(2) Low voltage and high current; With the reduction of the safe working voltage of the processor, the output working voltage of the customized power module has also decreased from the previous 5V to the current 3.3V or even 1.8V. The industry conjectures that the output working voltage of the LED advertising screen power supply will also drop below 1.0V.
(3) Apply mobile phone software to overall plan LED advertising screen power supply; In today's communication management system, the types of customized power module voltages are continuously added, and the development of power and integration also adds the difficulty coefficient of overall planning. The traditional overall planning and inspection of skills can no longer be used to the rapidly changing market demand. Therefore, it is the general trend to customize the auxiliary planning software of power modules.
