摘要
文章基于TI公司TMS320LF2407 DSP处理器,对新型三相不可控整流三相逆变器的软硬件进行设计,采用新的调制波重构SPWM技术可以减小直流侧电容,甚至去除直流侧电容,并能更好的逆变输出电压,提高输出功率因数和减小系统电流畸变率,通过仿真分析验证了其可行性。
This paper designed hardware and software of the new-style uncontrolled three-phase inverter based on TMS320LF2407 DSP processor. Reconstruction of the new-style modulated wave SPWM was adopted to reduce the DC side capacitance and even to get rid of it, in the mean time to invert the output voltage better and to improve the output power factor and reduce the current aberration rate. Its feasibility was verified by simulation analysis.
