SUMMARY In this research, an investigation on breaking of ice using a pulsed power generator for navigation of an icebreaker in an ice‐covered ocean is described. In these experiments, a pulsed arc discharge was formed using a Marx generator. In order to investigate the dependence of the input energy required for ice‐breaking on the circuit parameters of the generator, the capacitance of the generator was varied. The input energy for ice‐breaking was calculated from the waveforms of the electric power. It was found that the input energy for ice‐breaking decreased as the peak power increased with a decrease in the capacitance of the generator. © 2013 Wiley Periodicals, Inc.
