Simulation and analysis of the inverter output harmonic control technology

Yang Feng, Fei Yu, Shanshan Zhao

Abstract

Under the condition of large ship electric propulsion system, the simulation model of the system is established, and has taken deeply theoretical analysis and simulation on the characteristics and its inhibition technology of the system output voltage harmonic. For using PWM rectifier and PWM rectifier parallel LC output filter two kinds of methods to suppress harmonic wave are analyzed in the simulation, get the THD of output voltage under different switching frequency and different output frequency. Simulation results show that harmonics can be well suppressed with using PWM rectifier parallel LC output filter.
