N2 - The ideal theoretical spectral analysis for PWM has been available for decades. However, PWM actually suffers from non-ideal switching characteristics and their effects to the output spectrum have not been thoroughly studied theoretically due to the complexity involved. Transient ringing on both rising and falling edges is a common phenomenon during switching and it has been hold responsibility for harmonic distortion, judging from experimental results. In this paper, we will present a theoretical technique to model the PWM with transient ringing using a second-order circuit. This theoretical solution is the first of its kinds available in literature and it helps us to understand the distortion effects to the spectrum due to transient ringing. Simulations have been carried out to verify the correctness of the theoretical solution. © 2005 IEEE.
