Pulsed Current Transformer for Low Inductive Loads.
Abstract
At the US Army Research, Development and Engineering Command (ARDEC), an effort was undertaken to couple an array of five capacitor banks to a low inductance load. To achieve currents which exceed the limit placed on the capacitor banks, pulse current transformers were used. This power system, termed CAPSTAR, was ultimately used to electromagnetically stress a round bore composite railgun barrel section. A mathematical model has been developed to simulate a capacitor power supply driving a pulse transformer with various secondary loads. The model was first tested by comparison to experimental results using a subscale pulse transformer. The calculated data points were in good agreement with the experiment. Minor adjustments to some circuit parameters to account for the transitory behavior of the circuit are described. Keywords include: Electromagnetic railgun, Pulse transformer, Pulse power, and High current transformer.
