PWM逆变器特定谐波抑制技术
Specific Harmonic Suppression Technology for PWM Inverter
摘要
Abstract
In order to improve the quality of output waveform and suppress harmonic pollution of voltage type PWM inverter,the mathematical model of the output voltage of the voltage type PWM inverter is established and the harmonic distribution law is analyzed.The voltage type PWM inverter mathematical model was established based on SHEPWM,according to the specific harmonic elimination technique for solving nonlinear equations,switch angle data is obtained by using homotopy algorithm,which can guarantee fast convergence in a wide range of solutions of harmonic elimination equations.The simulation results prove the feasibility of this scheme.关键词
