modelingpower electronic converters at frequencies close to or above half the switching frequency has been difficult due to the time-variant and discontinuous switching actions. We develop a high-order generalized averaging method using the properties of moving Fourier coefficients to break though the limit of half the switching frequency. We also propose the high-order generalized average model for various switching signals, including pulsewidth modulation (PWM), phase-shift modulation, pulse-frequency modulation (PFM), and state-dependent switching signals, so that circuits and modulators/controllers can be modeled separately and combined flexibly. Moreover, using the Laplace transform of moving Fourier coefficients, the coupling of signals and their sidebands of different frequencies is clearly described as the coupling of moving Fourier coefficients of the same frequency in a linear time-invariant framework. The modeling method is applied to a PWM controlled boost converter, a V-2 constant on-time controlled buck converter, and a PFM controlled LLC converter, for demonstration and validation. Experimental results of the converters in different operating modes show that the proposed models have higher accuracy than exiting models, especially in the frequency range close to or above half the switching frequency. The developed method can be applied to almost all types of power electronic converters.

This article introduces a modeling framework for electric and hybrid propulsion systems and presents a comprehensive set of stability analyses with onboard experimental validations. In the studied electric powertrain, a diesel engine (DE)-driven generator set feeds a dc link via an active front-end (AFE) converter, forming a hybrid ac/dc power system suitable for battery integration. A state-space system model is established, and small-signal stability analyses are conducted with a focus on the control parameters. Two types of analysis are presented such as stability portrait and sensitivity analysis based on eigenvalues. The findings highlight complex interdependencies between the control parameters, including the measurement filters, and the proportional gains of control loops. The analytical model is benchmarked and validated against time-domain simulations and experimental tests conducted onboard a vessel with a hybrid electric powertrain. Results highlight the model's ability to mimic the real onboard power system under varying conditions, indicating the appropriate model fidelity and the ability to replicate the salient dynamic properties of the real system. The main outcomes include a detailed understanding of control parameters' interactions and the identification of unstable operating points. The findings demonstrate the practical value of the presented framework in enhancing the operational reliability of electrified vessels and facilitating efficient system integration.
