Mixed-mode LTD module

The paper proposes a mixed-mode LTD(linear transformer driver) module. Each brick of the mixed-mode LTD module is a multi-stage Marx circuit, where only the switches of the first several stages need external trigger, and the others work in self-breakdown mode. The analysis indicates that, the mixed-mode LTD module can effectively reduce the demand for external trigger; the independent structure of each brick can improve the maintainability of the module, and coupling trigger between Marx bricks can improve the reliability. The paper also discusses the effects of circuit resistance, magnetic core loss and self-breakdown switch jitter on the modules parameter design.
