摘要:
大功率逆变器开关器件容许开关频率极低,导致P W M 波形谐波较大。为解决此问题,对低开关频率下PWM 调制算法进行了分析和研究,并对研究得出的优化脉冲模式进行了Matlab 仿真和试验验证。结果表明:相应优化脉冲模式具备优良的输出效果;该脉冲模式可用于与具体控制算法相结合,以降低逆变器的输入、输出谐波。
Abstract:
The switching frequency of high power inverters is extreme low, so that the harmonic of PWM is very large. For solving the problem, a PWM modulation algorithm under low switching frequency was analyzed and studied, and the Matlab simulations and experiments were implemented for the optimized pulse pattern. The results indicate that the pulse pattern has excellent output, and can reduce input and output harmonics combined with specific control algorithm.
