A power converter is presented. The power converter includes a primary bridge unit coupled to a voltage source. Further, the power converter includes a secondary bridge unit coupled to a load. Also, the power converter includes a transformer disposed between the primary bridge unit and the secondary bridge unit and configured to magnetically couple the primary bridge unit to the secondary bridge unit. Additionally, the power converter includes a current sensor configured to measure instantaneous current flowing at an input terminal of the transformer. Furthermore, the power converter includes a cyclic state controller configured to receive the measured instantaneous current flowing at the input terminal of the transformer, and change a switching state of the power converter from a present switching state to a subsequent switching state based on the measured instantaneous current.
