Accurate design of Two-Phase Voltage Doublers based on a compact mathematical model

A novel accurate mathematical model to be applied in the steady-state analysis of Two-Phase Voltage Doubler circuits is presented. The use of this model in combination with numerical software tools provides a full understanding about the voltage doubler´s steady-state output behavior while, at the same time, accelerates and simplifies the design process of such circuits in comparison with the use of classical parametric SPICE-based simulations. Numerically simulated results show that the proposed model is closer to the SPICE-based simulation data than already developed models, offering less than 1% of relative error over a wide range of working load conditions.
