Abstract
Chaotic sequence is used for triangle wave spectrum chaotic spreading. Chaos triangle wave can be used for pulse width modulation (PWM) modulation, and then the reduction of harmonic content peak in sinusoidal pulse width modulation (SPWM) wave and the mechanical resonance, etc. can be realized. Due to periodic question and large computational complexity question of the traditional chaotic sequence mapping, this paper proposed a new double-chaotic sequence with mutual changing parameters mapping, and the corresponding method to generate SPWM wave was presented. This method was improved from traditional chaotic mapping equation Logistic chaotic mapping and combining Tent chaotic mapping. Compared with the traditional method for generating chaotic sequence, this method has a faster speed, better chaotic characteristics, costs fewer sources and can prolong the period efficiently. The chaotic mapping and SPWM modulation method based on field-programmable gate array (FPGA) is given and compared with other modulation method. The results show that the modulation method proposed in this paper can be finished easily and can reduce the harmonics peak effectively.关键词
