N2  -  <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>
