主 题：Switching frequency PWM harmonics EMI
摘 要：Switching frequency is an important factor in the performance control of power electronic *** can help optimize switching losses,switching ripples and electromagnetic interference,especially for newly developed high-switching-frequency silicon carbide *** variation in the switching-frequency methods has been developed for this purpose,especially the model-predictive variable switching-frequency pulse width modulation(VSFPWM)*** effect of periodic switching-frequency variation on the harmonics of a converter using double Fourier analysis and simulations are *** work verifies that the switching harmonics can be reduced by periodic variation in the switching frequency,and the low-frequency(baseband)harmonics only incur a slight *** analysis provides a theoretical foundation for the application of VSFPWM in power electronic converters.
