Advanced Electric Vehicle Battery System Powered by High-Frequency Inverter with Isolation Transformer Technology

The rapid growth of electric vehicles (EVs) necessitates advancements in charging technologies to enhance efficiency, reliability, and speed. Therefore, this project proposes an advanced high-frequency inverter with isolation transformer based EV battery system. The high-frequency inverter configuration designed for efficient energy conversion and storage. Starting with a DC supply, the inverter utilizes a sinusoidal Pulse Width Modulation (PWM) generator to produce high-frequency AC signals. This output is then directed into an LC tank circuit, which optimizes resonance for improved performance. An isolation transformer ensures electrical safety and stabilizes the system by decoupling the load. The parallel synchronous rectifier facilitates efficient power conversion, minimizing losses during the rectification process. PWM pulses are generated to regulate the output, ensuring that the energy delivered to the battery is both stable and efficient. A proportional-integral (PI) generator monitors and adjusts the system’s performance, maintaining the desired voltage levels. This system is particularly beneficial for renewable energy applications, enhancing the system’s reliability and efficiency. Overall, this project emphasizes advanced control techniques and component integration to achieve optimal energy management. The system’s versatility makes it suitable for various applications, promoting sustainable energy practices. Finally this project is implemented by DSPIC30F4011 Controller
