基于坐标变换电压跟踪型逆变电源的优化设计
Optimization design of inverter power supply based on coordinate transform voltage tracking model
摘要
Abstract
In high power devices, output voltage harmonic content of three-phase voltage type inverter power supply system is higher, a new type of three-phase inverter power supply is designed by using coordinate transformation to achieve constant voltage and constant frequency in closed loop control strategy, the single frequency doubling polarity SPWM modulation method is combined with a closed-loop feedback control method to realize voltage type tracking way, and it is combined with the LC filter circuit to reduce the load of the phase voltage harmonic content. Finally simulation model is built for system simulation. Through the contrast test, in a closed loop voltage tracker system, driving with linear load, the determined optimal modulation ratio m = 0.75; when a sudden adding perceptual load, the determined the optimal modulation ratio m=0.88, when a sudden adding capacitive loads, the determined optimal modulation ratio m=0.71. And then fast Fourier transform (FFT) is used to ana-lyze harmonic analysis tool, results prove that the new control method is better, to suppress harmonic wave and voltage waveform can improve.关键词
