A third‐order boost point of load converter capable of giving higher voltage gain, identical/similar to fifth‐order converters, is proposed. In view of the lower order and higher boosting feature, the converter is more suitable to interface the given low voltage source to a high‐voltage dc point of load or to a dc‐bus. Furthermore, the proposed converter dynamics is simpler as its control‐to‐output transfer function is free from right half s ‐plane zeros. Component design expressions are formulated through a steady‐state analysis. The boosting factor of the proposed converter is higher than the traditional boost and other reported fourth‐order boost converters. The transfer functions are formulated from the state‐space model and then a digital controller is designed in the z‐domain. The proposed converter features are demonstrated through analysis and then compared with sample experimental observations.
