Precise variable output voltage control of boost converters has wide possibility of industrial applications. However, it is challenging owing to the nonlinear and nonminimum phase characteristic of the boost converter. In a previous study, the authors have proposed a nonlinear noncausal feedforward control method for precise control, and the experimental varidation was shown for a small load. This study verifies the validity of the proposed nonlinear noncausal feedforward control with current and voltage feedback control with a 10kW load, which is 500 times greater than the conceptual validation of the previous paper. The result confirms the effectiveness and validity of the proposed control method on a practical boost converter system.
