基于DSP的混合型矿用应急电源逆变器的研制

Develop of Inverter of Mixed Type Emergency Power Supply in Mine Based on DSP

论述了以DSP为控制器,利用不规则采样法产生SPWM波、输出电压的FFT变换以及恒压频比(V/F)控制算法实现了应急电源逆变器变频起动以及稳态时利用PI调节实现电压稳定输出,实验验证了设计的可行性,性能达到了国标要求。

SPWM wave produced by the anomalistic sampling method, FFT conversion of output voltage and （V/F） constant voltage frequency ratio control arithmetic is used to complete frequency conversion start of emergency power supply, also the PI adjusting method is to stabilize the output voltage in the steady state, experiments indicated the design is feasible, the performance reach requirements of country standard.
