Developing a new type of impulse voltage generator by method of the controllable capacitor charging for simulating experiment of the upward lightning leader, it is urgently needed to solve realization issue of the flyback transformer of high voltage and high power, which is the main component of such new generator's core circuit. Based on the circuit of controllable capacitor charging applied to simulation of the electric field in temporal characteristics, technical requirements for the flyback transformer were researched and proposed, and then concrete electromagnetic structure of the flyback transformer was researched and designed, which centered around technical difficulties for the realization of such kind of transformer. Furthermore a prototype transformer was developed, and application performance of the transformer was testified by experimental simulation of the electric field in temporal characteristics. The key technical issue for development of a new type of impulse voltage generator was solved.
