  During the last 30 and 40 years, TS transformer substations have evolved a lot, from the classic assembly in open areas, partition walls and outdoors, to the existing model, in order to increase human safety and material reliability, as well as significant progress. Assembly and space reduction, new results such as metal enclosures, prefabricated buildings, compact transformer substations and finally installed substations are also revolutionary. Due to society's increasing concern about the environment, the industry as a whole is rethinking the design and materials that may mean pollution, trying to replace them as much as possible with environmentally friendly communities. The inevitable development of society cannot and should not destroy the future of the earth. The time for sustainable development has come. So our work here today is a help in that sense.

  <p class="Abstract">In this research, the structure of a Full-bridge converter has been used to feed the klystron amplifier. Three Full-bridge transducer modules with high voltage transformers are used to supply the power of klystron (100 kW, 4 kV, 25 kV). The output of the transformers is rectifier in a star structure and after passing through a &pi; filter, the circuit of the klystron lamp is supplied. The output of the power supply is 1 ms width and frequency of repetition is 50 Hz. The input voltage of the converter is 500 VDC, which is supplied by a three-phase feed. In this research, by balancing the magnetizing current of high frequency transformers, the maximum magnetization current of transformers decreases and decreases the maximum current of transistors. In addition, the core dimensions of the transformer decrease by reducing the maximum magnetization current. As a result, the dimensions, volume, and weight of the klystron drive circuit are reduced. Also, by using leakage inductance of high frequency transformer, series resonance circuit has been created and soft switching conditions have been provided. In this way, it improves the performance of the klystron driven circuit. Modulator performance has been simulated and approved using PSCAD software and resistive load.</p> Manuscript profile
