基于DSP的3kW高频开关电源的设计

Design of a 3kW high frequency switching power supply based on DSP

结合开关电源发展的现状,将数字控制技术应用于开关电源,设计了一款数字控制方式的20 kHz/3 kW开关电源。对其主电路和控制电路进行了理论设计和参数估算,介绍了基于DSP的数字化电源的控制电路设计方案。实验结果表明系统设计可行,性能指标基本可以满足设计要求。

Combined with the development of switching power supply, the digital control technology was applied to switching power supply. A 20 kHz/3 kW switching power supply based on DSP was designed in this paper. In the article, the main circuit and control circuit were designed in theory and the related circuit parameters were estimated. The experimental results show that the system design is feasible, and its performance indicators can meet the design requirements.
