N2 - This paper proposes the sinusoidal third harmonic voltage injection pulse-width modulation method for applying the LCL filter to Vienna rectifiers. The LCL filter can lead to the resonant problem in the CL part of LCL filter. This problem generates the current oscillation at the resonant frequency; therefore, the system using LCL filter becomes unstable. To overcome this problem, the controller bandwidth, switching frequency, PWM method, and active damping method are considered in design process. However, the existing PWM methods for the full power factor operation generates the resonant current. The proposed method injects the sinusoidal third harmonic voltage to the sinusoidal reference voltages. The magnitude and phase of the injection voltage are determined depending on the modulation index, power factor, filter impedances, and grid magnitude. Compared to other PWM methods, the probability of the resonant problem due to the PWM method is eliminated by using the proposed method. The effectiveness and performance of the proposed sinusoidal third harmonic voltage injection method are verified by simulation.
