Abstract

A study was conducted to find the effect of the power transmission line on the measurement of transient voltages across a pulsed arbitrary thruster with a passive power supply. A lossless transmission line was modeled and the response of this line using the relationship between the voltage at any two adjacent nodes and the current flowing through two adjacent inductors was derived. The resonance of transmission line appearing in the transfer function significantly emphasize certain frequency components of the input signal, even for voltage measurements made relatively close to the source. The results show that pulsed plasma thrusters having no transmission lines determine the effect of resonances on the measurement of voltage transients. Elimination of resonances is carried out by either suitably relocating the voltage measurements or by accurately measuring the transfer function.
