Abstract

The present invention provides a transformer capable of generating fragmentary voltages, wherein the coil is placed in a closed magnetic conductive shell. The central post of the magnetic conductive shell exactly passes through the center of the coil, so that the magnetic lines generated by the current inputted to the primary coil are uniformly distributed to surround the peripheral of the whole coil by using the magnetic conductive shell and its central post. Therefore, based on the circumference ratio of the secondary coil wound on the peripheral of the central post, it is applicable to determine the ratio of the magnetic lines of the secondary coil that cuts and passes through the central post, and the output values of the fragmentary voltages on the wires drawn from different positions of the secondary coil.

The induced voltage generated by I is limited to an integer multiple of the input voltage (such as an input voltage of IV, which produces an output voltage of 5V or 10V ...). If an output voltage with a sporadic voltage (such as 4.3V) is required, then A step-down circuit needs to be installed outside the voltage generator to reduce the output voltage to the required voltage value. In this way, not only the complexity and manufacturing cost of the entire transformer can be increased, but also the transformer and related circuits cannot be effectively reduced. The volume also causes unnecessary loss in power and increases circuit parts, so it is not ideal in use. Summary of the Invention: In view of this, in order to improve the shortcomings of the conventional device structure, the inventor has finally developed and designed a transformer capable of generating sporadic voltages after long-term research and experiments.
