Abstract

   Vacuum microwave devices, which are used in some of radar systems, work under high power pulse voltage, and this pulse voltage are generated by high power supply which called the modulator in radar systems, one of important part of modern modulators is the high-power pulse transformer which is an indispensable component of power system which performs many functions such as voltage transformation, electrical isolation, noise decoupling and power quality improvement. Relatively, pulse transformer has the advantages of compact structure and excellent repetitiveness.

     Because of the output pulse shapes, especially the rising and falling phases are determined by the design of the pulse transformer and its parasite elements such as its leakage inductance, distributed capacitance, magnetization inductance, and step-up ratio.

The more compact the impulse transformer is , the fewer turns it has and hence they are having low leakage inductance and distributed capacitance, so it is very important to determine the allowed values of these parasite elements to obtain the desired shape of voltage pulses which have the essential effect on radar working and its specifications.

     In this paper, the principle, type and characteristics specification of this high-power pulse transformer are shown.  And reporting the simulation results of design method, and construction results, where aiming at this purpose is to obtain high voltage pulses with good specification as a short rise/fall time, non-droop voltage and expanding output pulse-width, which will be helped in building of high-power pulse modulators to use it for modern our Syrian radars.
