三相频率可调的逆变电源设计

Design of three-phase Frequency Programmable Inverter Power Supply

本文用TMS320LF2407A DSP芯片设计了一种采用SPWM调制策略的IGBT三相全桥逆变电路.对采用数字信号处理(DSP)实现的数字控制技术进行了深入研究,将SPWM调制策略与数字信号处理器(DSP)相结合,实现了输出频率可调(0～50 Hz),并通过仿真和试验验证了理论分析.

in this paper, a IGBT Three-Phase Full-Bridge Inverter used the SPWM(Sinusoidal Pulse-Width Modulation)modulation strategy based on TMS320LF2407A DSP is presented. The research under the numerical control technology has been done, which used the digital signal processing (DSP), combining the digital signal processing (DSP) with the SPWM modulation strategy, realize the variational frequency can be exported (0~50Hz), and confirmed the theory analysis results through the simulation and the experiment. Experimental data shows satisfactory feasibility of the method.
