The invention relates to an integral ring transformer with a bottom plate and an inductance and a production process thereof. The integral ring transformer comprises a transformer fixed bottom plate,a fixed assembly, a ring inductor and a ring transformer main body. The inductance coil is provided with two taps, the primary coil is provided with two taps, the secondary coil is provided with at least two taps, the primary coil is connected with the inductance coil, the second tap of the primary coil and the second tap of the inductance coil are used for receiving the input voltage, and the tapof the secondary coil is used for outputting voltage. The fixing assembly comprises a center fixing cap and a center fixing member. The central fixing cap is provided with an internal thread structure, and the central fixing part is provided with a fixing rod with a fixing end head and an external thread structure. The fixed end is fixed on the fixed bottom plate of the transformer. The fixing rod is matched with the central fixing cap; Fixing resin so that the central fixing cap is immersed in the fixing resin. The fixing resin is cured, and the position of the central fixing cap is fixed. The transformer is manufactured according to the production process, and the effect of fixing the ring transformer main engine is achieved.
