According to the abstract released by the Intellectual Property India: "This project presents the design and implementation of modulation techniques for hybrid power converters in electric boat propulsion systems. The proposed system utilizes a battery-based energy source integrated with a hybrid power converter to efficiently manage and regulate power flow to the motor. Advanced modulation techniques such as Pulse Width Modulation (PWM), Sinusoidal PWM (SPWM), and Space Vector PWM (SVPWM) are employed to control switching operations and improve output performance. The system incorporates key components including a DC-DC converter, inverter, sensors, gate driver, and controller (MCU/DSP) to ensure precise control and monitoring. These techniques help in reducing harmonic distortion, minimizing switching losses, and enhancing overall efficiency. The implementation enables smooth speed and torque control of the motor, improving propulsion performance under varying load conditions. Furthermore, the system enhances battery utilization, ensures safe operation through continuous monitoring, and extends the lifespan of components. The proposed design provides a reliable, energy-efficient, and environmentally friendly solution for modern electric boat applications."
