Description
Linear transformer driver (LTD) is an alternative pulsed power generation scheme to traditional pulse compression methods. Solid-state LTDs are being developed for industrial applications. They have advantages in system modularity and output flexibility. In addition, they are also featured by compactness and stress distribution.
Semiconductor power devices have been used as switches for the LTDs. The output voltage and current of an LTD system are determined by the number of modules and the number of switching devices in each module. The rise-time and pulse-width depend on the specifications of the switch and the circuit inductance.
Experimental studies have been carried out on the development of hybrid LTD, bipolar LTD and smart LTD. The hybrid LTD uses both MOSFETs and IGBTs as switches so that the system output can benefit from the merits of both devices. The bipolar LTD can generate bipolar output with arbitrary combination. The smart LTD is characterized by waveform variation and feedback control.
