whats the trend and significance of Digital Control System Based on SCM? What is its advantage?

With more and more applications of inverter power supplies, the demand for the development of inverter power supply technology is also increasing. At present, the design of inverter power supply adopts a structure composed of discrete components designed by pure hardware. As the number and type of appliances used by people increase, the higher the waveform and capacity requirements of the inverter power supply, the higher the complexity of the inverter power supply design and the more components used. However, due to the excessive number of components and the poor stability of the power supply, the entire system is often damaged due to poor quality of a component.

In addition, the traditional inverter power supply is based on the design of analog components and has no programmability, which makes the reversible power supply less scalable and has no display function. Therefore, the microcontroller is very important as the master chip of the inverter power supply.

With the development of large-scale integrated circuits and digital control technologies, microprocessor-based (MCU)-based digital controllers have become more and more widely used in inverter power supply control systems. The digital control hardware circuit has a simple structure, strong anti-interference ability and high reliability, and can realize the advantages of advanced control algorithms and real-time control; The change of control strategy can only be achieved by rewriting the software. Flexible control, easy commissioning and maintenance.

The detailed advantages it can bring to the user, we will gradually elaborate in the follow-up articles
