“…To design the sonar transmitter, the circuit diagram is shown in Figure 2. Here, the BVD (Butterworth-Van Dyke) model is used for the equivalent circuit model of the transducer [3,9,21]. The transmitter's topology consists of the full-bridge inverter converting DC to AC, a low-pass output filter reducing THD, and a matching circuit using a magnetizing inductance of the transformer.…”

“…In recent years, the applications of acoustic transducers and transmitters have been expanded for sonar, medical, communications, and industrial purposes [1][2][3][4][5][6]. The mechanical and acoustic operations of an acoustic transducer are generally expressed as an electrical equivalent circuit model [7][8][9].…”

“…To design a medium-voltage converter, it is important to consider the parasitic elements of the transformer, because the parasitic capacitance can affect its efficiency and control method [22]. Song et al proposed the design method of matching and filter circuits by using only transformer magnetizing inductance [3]. Kim et al proposed an LC matching technique for a class B amplifier driving high directional piezoelectric transducers [23].…”

“…As can be seen in previous papers, studies of sonar transmitters have not presented a variety of views beyond ultrasonic transmitters. Recently presented papers have focused on either the matching/filter design or the PWM control, but not shown the integral system [3,16,21]. This paper presents the design and control of a sonar transmitter for the widely distributed impedance load to which the study field is generally inaccessible.…”

“…This paper presents the design and control of a sonar transmitter for the widely distributed impedance load to which the study field is generally inaccessible. The underwater acoustic transducer was developed to be driven both in multiple channels and in high-power conditions for achieving the detection ability of active sonar systems [3,17,[24][25][26]. To control phases of transmission signal among transducers, the transducers are required to be independently driven [17].…”

For driving multichannel underwater acoustic transducers, the integrated design of the transmitter based on the analysis of the widely distributed impedance should be considered. Previous studies focused on either the matching circuit or the fast resonant tracking control. This paper proposes the design and control methods of a sonar transmitter based on the analysis of the impedance distribution. For the transmitter design, the optimization method based on the particle swarm optimization (PSO) algorithm is proposed for estimating the equivalent and matching circuit parameters. The equivalent circuits of the transducer are more precisely designed by using the measured data in both air and water. The fitness function proposed in the matching includes special functions, such as the limitation and parasitic inductances. A comparison of the experimental and simulation results shows that the optimized matching design improved the power factor, and was similar to the experimental result. For the transmitter control, the constant power and voltage control (CPVC) and instant voltage and current control (IVCC) methods are proposed for the variable impedance load. The impedance variation range affects the rated power and rated voltage of the transmitter, and the rating range determines the initial modulation index (MI) of the pulse-width modulation (PWM) control. To verify the control method, an experimental setup including the multichannel acoustic transducers was established. As a result, the constant power and constant voltage were verified with the proposed control, and the instant voltage and current control also worked in the event that the instant voltage or current exceed their threshold values.
