Design of a regulator for multi-pick-up systems through using current offsets

In this paper, we introduce a novel regulator for the On-Line Electric Vehicle (OLEV) system and an algorithm of the regulator controller. The OLEV has five pick-ups. The regulator has ten boost converter modules which use dual Proportional Integral (P-I) controllers controlling the output voltage of the modules. This regulator also keeps a balance between the 1^st pick-up coil´s rectified current and the 2^nd pick-up coil´s rectified current and a balance between the 1^st pick-up coil´s rectified voltage and the 2^nd pick-up coil´s rectified voltage. According to the Pulse Width Modulation (PWM) interleaving technique, the output current ripple and the output voltage ripple of the modules are minimized. Using the proposed regulator, we can achieve the stable and high output voltage suitable for battery charging.
