Abstract
A model for an inductorless step-up piezoelectric-resonator-based DC-DC (SUPR) converter is presented. A describing function approach is used to determine the equivalent circuit of the MOSFET power stage and resonator, allowing the duty cycles of both MOSFETs to be accurately estimated. The model provides a method for estimating the output voltage and resonant current of the converter during operation. The accuracy of the model is verified against experimental and simulation results, with a less than 1.5% mean absolute percentage error in voltage gain estimation, compared to experimental measurements. Design guidelines for optimal operation of the converter are also presented.
