Industrial control power supply manufacturers introduce the development history of power modules

With the rapid development trend of power electronics technology, power engineering electronic products are increasingly closely related to everyone’s work, food, clothing, housing and transportation, and electronic products are indispensable for reliable power supplies. In the 90s, computer power supplies have fully implemented power supply modular design. Especially in recent years, due to the rapid development of data services and the continuous marketing and promotion of distributed system power distribution lines, the equipment increase of power supply modules has already exceeded that of multiple power supplies. Industrial control power supply manufacturers said that with the many applications of semiconductor material processing technology, packaging technology, and high-frequency soft power switches, the power of the power module is getting bigger and bigger, the conversion efficiency is getting higher and higher, and the application is getting easier and easier.

The power supply module is a switching power supply that uses contemporary power electronic technology to control the time ratio of the activation and opening of the circuit transistors to maintain a stable output operating voltage. The power supply module is usually composed of pulse width modulation (PWM) control IC and MOSFET. Comparing the power supply module and the linear regulated power supply, the cost of both increases with the increase in power, but the speed of the increase is different. The cost of the linear stabilized power supply is higher than the power supply module at a certain power point, and this cost is a turning point. With the development trend and independent innovation of power electronics technology, the power module technology is constantly innovating independently. This cost turning point is gradually moving to the low-output power engineering end, which gives the power module development trend prospects in many aspects. The development trend and application of another power module have key practical significance in terms of resource saving, energy saving and ecological environment protection.

The development of semiconductor material integration, power module packaging and power circuit topology has brought the power module to a new upgrade level, and the power module is developing towards the component level step by step. With the promotion of flexible production and integrity design of power modules, the use of control modules has gradually become standardized, the use of power circuits has become easier and easier, and the selection of motors has become easier. Various power module manufacturers have just begun to integrate components and power circuits to control costs as much as possible and enhance their competitiveness.
