摘要
对变频空调中采用基于平均对称规则采样算法的SPWM技术进行系统全面分析,给出死区时间对基波输出频域的影响,并建立了定量计算的数学模型,提出了一种实用的死区补偿算法,并在 1台
Based on the algorithm of average symmetric regular sampling,the paper analyses the performance of SPWM systematically.The deadtime effect on the output is given.the models of calculation are setup.Finally,an useful algorithm of compensation is introduced.these are verified in a 5kW locomotive inverter airconditioner.
