Title: Low voltage power system for a towed acoustic array

Abstract: A low voltage power system for a towed active array sonar is provided. The ow voltage power system includes a shipside power supply driving a step-up transformer which is connected to the tow cable transmission line. The transmission line is connected to a second step-up transformer which provides the signal voltage to the active transducer. The transducer signal voltage is also used to drive a rectifier and DC power supply which provides DC bias voltage to the transducer. The DC voltage is isolated from the tow cable by a blocking capacitor.
