1 Introduction With the improvement of the modern automation level of power systems and the increasing complexity of high-frequency switching power supply structures, people are encouraged to adopt new control methods to quickly reflect module changes, so as to greatly improve the stable operation level of switching power supply modules. In the entire control system. There are more and more algorithms for processing sampled data and algorithms. Traditional microprocessors such as MSC51 series have gradually reduced the internal integration resources, complicated peripheral circuits, poor anti-interference ability, and are not good at data processing. Can not meet the needs of high-tech level.
The MSP430 series of microcontrollers is a 16-bit ultra-low power mixed-signal processor that Texas Instruments (TI) introduced to the market in 1996. Due to its ultra-low power consumption, powerful processing power, high-performance analog technology and rich The on-chip peripheral modules and the stable, efficient and efficient development environment of the system have been highly praised by users. This article uses MSP430 microcontroller to control the stable operation of switching power supply.
2 System Design This system adopts MSP430F155 type single-chip microcomputer to realize stable control of switching power supply, mainly including the following parts: MSP430 core part, feedback signal processing part, signal output given part, control circuit part, communication part and CPU peripheral circuit. The overall structure of the system is shown in Figure 1:
