AC-DC power converters; soft switching; statespace method

In AC-DC power conversion, the input source features: time dependence and phase angle, combined with the complexity of resonant circuits, lead to solutions that are difficult to obtain. In this sense, an analysis and design methodology of resonant rectifiers is proposed, in which, iterative numerical solutions are replaced by analytic solutions with the help of computer algebra systems. The method allows obtaining the AC-to-DC transfer function, the quality factor, the phase angle and the resonance frequency. A case study for the Class-E zero-derivative voltage switched resonant rectifier is performed. Experimental results are shown in order to validate the theoretical approach.
