Abstract

Abstract

A repetitive linear transformer driver(LTD) based on IGBTs has been tested. The device has four 3 300 V/1 200 A IGBT switches and corresponding drivers, buffer circuits, capacitors, and magnetic core. It can output 4.3 kA current on 0.57 Ω load and achieve a 200 Hz repetition frequency at burst mode. The test result shows that the LTD based on IGBTs can work in repetition mode and the LTD circuit can enhance the operation voltage of IGBTs. Core saturation and reset problems are also analyzed, and an effective method to solve core saturation without reset is proposed.
