Abstract

Acoustic transmitters used in underwater communication system typically utilizes the PIEZO-Electric elements in their construction. The PIEZO-Electric sends data when it is supplied by an AC voltage in an operating period. The water depth in a location where the transmitters are operated determines the required supply voltage level of the transmitter. A high-efficiency high step-up high-power density (HHH) converter plays a critical role in supplying PIEZO-Electric transmitters in underwater applications. Moreover, the PIEZO-Electric transmitters (PZETs) must occupy a small space for underwater applications. Hence, a DC-DC HHH converter is proposed in this paper which is able to operate in zero voltage switching (ZVS) conditions; while the absence of a transformer or any coupled inductor in the topology significantly improves the power density. In this paper, when the DC-DC HHH converter increases voltage level to the desired value, a full-bridge converter provides required AC voltage to supply the PZETs. Simulation results demonstrate the effectiveness and high efficiency of the proposed converter during supplying a PZET. Also, a converter prototype is implemented to demonstrate the performance of the converter in the provision of soft switching as well as boosting.
