The utility model discloses a multi-stage voltage output type transformer which comprises five permanent magnets, five secondary coils and primary coils. The five permanent magnets are fixedly gathered, the primary coils are evenly wound around the surface of a prism where the permanent magnets are gathered, and the five secondary coils are evenly wound around the surface of the prism on the outer sides of the five permanent magnets respectively. According to the multi-stage voltage output type transformer, through the mutual effects of five identical permanent magnets, the primary coils of different turn numbers wound around the prism on the sides of the permanent magnets and the primary coils wound around the gathered prism of the permanent magnets, the requirements of outputting different voltages in the same environment are met, and the loss of electric energy in the voltage transformation process is also reduced.
