Abstract

In this paper, the effect of phase shift technique on the performance of a power modulator with output characteristics of-25 kV, 5 A for the Klystron amplifier is investigated. This modulator is composed of a DC-DC converter structure with three high frequency transformers in a three-phase structure. In this circuit, the voltage of 500 VDC is converted to-25kV pulse. DC-DC converter structure, consists of three full-bridge converter modules with high frequency transformer. In this research, by using switching phase shifted, the transformer magnetic current is balanced and reduces the current stress of the switches. The series resonance circuit has also been used to reduce switching losses. The function of the converter is simulated and verified by PSCAD software.
