1. Introduction: As modern power systems continue to evolve with higher levels of automation and the increasing complexity of high-frequency switching power supply structures, there is a growing need for innovative control methods to respond swiftly to module changes. This ensures improved stability and efficiency within the entire control system. However, traditional microprocessors like the MSC51 series face limitations such as limited internal integration resources, complex peripheral circuits, weak anti-interference capabilities, and inadequate data processing abilities, making them unsuitable for advanced technological applications. Introduced by Texas Instruments (TI) in 1996, the MSP430 series of microcontrollers is a 16-bit ultra-low-power mixed-signal processor that has garnered significant praise from users due to its ultra-low power consumption, strong processing power, high-performance analog technology, and rich on-chip peripheral modules. Additionally, its stable and efficient development environment further enhances its appeal. This article explores how the MSP430 microcontroller can be used to ensure the stable operation of switching power supplies. 2. System Design: This system utilizes the MSP430F155 single-chip microcomputer to achieve stable control of switching power supplies. It includes several key components: an MSP430 core section, a feedback signal processing section, a signal output section, a control circuit section, a communication section, and a CPU peripheral circuit. The overall structure of the system is illustrated in Figure 1 below:
