Abstract: An isolated power converter and a hydrogen production system are provided. An electrical connection structure in the isolated power converter includes N secondary winding output bus bars, N rectifier circuit input bus bars, and a positive-negative bus bar, where N is greater than or equal to 1. A secondary winding may include M tapping points, and the secondary winding output bus bar and the rectifier circuit input bus bar that correspond to the secondary winding each include M copper bars that are insulated and stacked. The M tapping points of the secondary winding overlap the M copper bars of the secondary winding output bus bar at input ends of the M copper bars, respectively. The positive-negative bus bar includes two copper bars that are insulated and stacked.
