Influences of Cell-Driving Sequences on Performances of Magnetically Insulated Induction Voltage Adders

Based on the transmission line code model, influences of cell-driving sequences on both cell feedings and load voltages of a 12-stage magnetically insulated induction voltage adder were analyzed. Simulation results show that the cell-feeding voltages are obviously distorted under nonideal IVA sequences. The distortion degree (such as overshoot voltage and reverse voltage) would be greater as the increment in the parameter n (the amount of cells that are synchronously driven per each group). These phenomena were analyzed in detail and well explained on the basis of transmission line theory. Simulation results also show that the rise time (10%-90%) of load voltages increases as the increment in the parameter n, while the flattop time decreases gradually, which leads to longer rise time and shorter flattop time. But the alterations of the load peak and reverse voltages are negligible. These characteristics indicate that a wide variety of voltage-pulse shape can be formed by varying cell-driving sequences.
