摘要 常规正弦脉宽调制(Sinusoidal pulse width modulation,SPWM)的输出波形在载波频率及倍频周围含有较高谐波成分,基于混沌理论提出了一种新型脉宽调制(Pulse width modulation,PWM)原理——混沌正弦脉宽调制 (Chaos-based sinusoidal pulse width modulation,CSPWM),其三角载波信号的频率按一维混沌映射帐篷函数规律变化,从而改变谐波的频谱分布,使谐波连续均匀分布在较宽的频带范围内,抑制了由谐波引起的电磁噪声。将 CSPWM应用于电压型逆变器,结果表明,其有很好的谐波抑制特性,且用单片机实现简单。 There exists cluster harmonics around the multiples of carrier frequency in conventional sinusoidal pulse width modulation (SPWM) output waves. A new strategy for generation of Chaos-based SPWM (CSPWM) is proposed with the aim of reduction harmonic. A one-dimensional tent map is used to vary the frequencies of the triangular carrier wave so that the harmonics can be distributed continuously and equably over a wide frequency range. The new proposed CSPWM scheme is applied to a voltage source inverter. Research results show that it is effective on suppression of harmonics, moreover, it is easy to realize by microprocessor.
