High Repetition Pulse Generation by using Small Type Transmission Line Transformers

Abstract

Stacking of voltage pulses by using small type transmission line transformers (TLT) is described. By using power MOS-FETs for switching devices, repetition frequency of output pulses can be several hundred kilohertz. Temperature rise of the ferrite bead core for TLT increases with repetition frequency and common mode voltage of TLT. Relation of the rise time, load resistance, and number of cores were investigated.
