Abstract

PURPOSE: To protect a semiconductor element constituting a power unit from damage due to the high voltage, by discharging electrical energy into the sea water in form of thermal energy when the voltage of the power unit rises to a level higher than a prescribed value.
CONSTITUTION: A detector 12 for the purpose of detecting voltages 11a, 11b at the putput end of a detected power unit is provided. At the time of detection that output 12a of said detector 12 exceeds a certain reference voltage corresponding to a regeneration mode, contacts 15a, 15b are closed by a regeneration mode detector 13. If the contacts 15a, 15b are closed, a controller 14 is operated so as to discharge excessive electric power from electrodes 19a, 19b into the sea water.
