Abstract: A novel bi directional drive for the BLDC motor powered by a Photo Voltaic source is presented. Instead of the conventional DC rails the BLDC motor is powered by AC rails with AC voltage amplified by resonance created by an LC tank circuit. The three legs of the conventional BLDC motor drive with six switches are replaced by six bidirectional switch modules. The MPPT algorithm is implemented in the front end DC to AC converter of the H bridge type terminated on the AC side across a resonating tank circuit. A battery charging arrangement is also provided with bi directional power transaction feature. The methodology is suitable for the BLDC drive adoptable in three wheeler vehicles. The MATLAB SIMULINK model has been developed to prove the efficacy of the proposed system and it has been validated using experimental hardware setup
