Abstract :

The rapid growth of Electric Vehicles (EVs) necessitates advancements in charging technologies to enhance efficiency, reliability, and speed. Therefore, this work proposes an advanced high frequency EV battery charging system incorporating isolation transformer technology to enhance safety, efficiency, and power quality. The Bridgeless Canonical Switching Cell (BLCSC) converter for improving input power quality by reducing harmonics and performing Power Factor Correction (PFC). The high frequency inverter and an LC tank circuit optimizes resonance for improved performance. An isolation transformer ensures electrical safety and stabilizes the system by decoupling the load. The parallel Synchronous Rectifier (SR) facilitates efficient power conversion, minimizing losses during the rectification process. Pulse Width Modulation (PWM)  signals, generated by a DSPIC30F4011 controller, along with Proportional Integral (PI) controllers, maintain accurate regulation of voltage and current during battery charging. The proposed system implemented MATLAB simulation that achieves a converter efficiency of 95% and maintains a Power Factor (PF)of 1, ensuring high performance operation. This system is compact, renewable energy compatible, and supports fast, sustainable charging.
