“…The test is carried out by adjusting the frequency value generated by IC SG3525 gradually by changing the RD value as written in Equation ( 1), until the lights are dimmed or extinguished. A dim or extinguished light indicates that the transformer is matched because the current from the primary winding is maximally transferred to the secondary winding [35,36]. From the test results, it can be revealed that the EE42 transformer is matched at a frequency of 50-60 kHz.…”

The size of the iron core transformer in an inverter is large and heavy because it has more conductor turns and works at low frequencies. In contrast, ferrite core transformers are designed to work at high frequencies, so the number of turns of the conductor is less, and the transformer size is relatively small and light. Device portability is a significant challenge in designing high-power inverters. This research uses a ferrite core transformer to design a portable pure sine wave inverter. A two-stage technique is proposed in designing the inverter so that the dc-link voltage and capacitor size can be flexibly selected, and the device size can be compacted. The design consists of two stages. First, a circuit to generate a 400-Volt DC voltage is designed using IC SG3525, a MOSFET power amplifier, and a ferrite core step-up transformer. Second, a pure sine wave generator circuit is constructed using an EGS002 module, MOSFETs, and a filter circuit. Experiments are performed by measuring the output voltage, monitoring power and frequency, and observing the waveform with an oscilloscope. The results reveal that the designed inverter can generate a 220-volt pure sine wave output, a maximum power of 500 Watts, a frequency of 50 Hz, and an efficiency between 91.4% to 98.1%.

“…As depicted in Figure 1, traditional SONAR amplifier operation involves the generation of voltage in a sinusoidal waveform for SONAR through high-speed switching of the converter, resulting in sine-wave synthesis and high-frequency removal via the LC filter. Furthermore, to address problems related to the quality of the harmonic content in the voltage applied to the SONAR sensor and volume-related concerns of the converter, a matching frequency within the operating frequency range of the SONAR sensor was selected to design a matching transformer, as discussed by previous researchers [15,16]. Additionally, an efficient power amplification method using the Class E technique has been proposed to address the efficiency problems arising from power converter switching [16].…”

“…In the first approach, an equivalent electrical circuit with impedance and phase matching at the matching frequency of the SONAR sensor is derived, and the inductance value for reactive power removal is designed using these parameters. Subsequently, the SONAR load, including the matching transformer, is equivalently transformed into a single resistance, and the LC filter parameters are derived to match the cutoff frequency [15]. However, this approach does not consider the parasitic elements within the LC filter and matching transformer, which leads to discrepancies between the design characteristics and actual performance.…”

In recent years, there has been a trend toward expanding the operating frequency range and increasing the output power of Sound Navigation and Ranging (SONAR) systems to enhance their acoustic detection capabilities. However, due to this increase in operational power, the electrical capacity of amplifiers for SONAR system operation also increases, necessitating High-Power Amplifiers. When configured with a single amplifier, as in conventional methods, the volume of amplifiers increases due to volumetric increases in heat dissipation, components, and windings. These issues are detrimental to SONAR amplifier installation, mobility, maintenance, and equipment lifespan due to stress on individual components. Additionally, amplifiers for SONAR systems are comprised of power conversion devices, transformers for LC filters and matching, necessitating consideration of LC filters and matching transformers for enhancing voltage quality and efficiency to improve amplifier performance transmitted to SONAR transducers. However, previous research has focused on single-amplifier design methods, neglecting such considerations. Therefore, this paper proposes a design technique that overcomes the drawbacks of using the conventional design method by configuring multiple H-bridge inverters in a cascade format and utilizes one of the optimization algorithms, Particle Swarm Optimization (PSO), to derive amplifier design techniques that optimize component parameters for enhancing high-capacity amplifier performance. Subsequently, theoretical analysis, simulations, and experimental results comparing the proposed high-power amplifier design method with conventional single-amplifier design methods demonstrate similar error rates in operational frequency bands.
