基于CORDIC算法的三相SPWM发生器设计
Design of three-phase SPWM generator based on CORDIC algorithm
摘要
Abstract
SPWM⁃based three⁃phase inversion technology is widely applied in many areas,such as speed governing trans⁃mission,power switching and power electronics control. A three⁃phase SPWM generator which samples with asymmetry rule is designed in the paper to improve the accuracy and efficiency of the three⁃phase SPWM. The modulation sinusoidal signal is achieved by an improved iterative algorithm CORDIC,which dispenses with occupation of a lot of memory space as the LUT does. The output signal of SPWM is obtained by comparing the irregular sampling of isosceles triangle wave and modulation sine wave. The modular programming design is realized via Verilog HDL under the Quartus ii compiler platform. The efficiency and accuracy of the design were verified by waveform simulation. The design is suitable for high⁃precision three⁃phase inverter sys⁃tem and can also be combined with other modules to be applied to sinusoidal drive of various three⁃phase motors.关键词
