This paper illustrates a wide voltage gain multi-output DC-DC converter for electric vehicle application. The proposed converter provides a reconfigurable resonant network. The resonant network can operate in either of the LLC or LLC-C modes operating in a wide voltage gain along with dual output. Additionally, the converter can provide good voltage regulation over a narrow frequency range. This converter also having soft-switching and inherent over current protection features in LLC-C mode. The proposed converter is designed to regulate the dc-bus voltage by using frequency modulation control. The hysteresis band current control is implemented in inverter for controlling the BLDC motor. A 1kW BLDC motor drive is analysed and simulated using different reconfigurable resonant network. The simulation results are shown for driving two BLDC motor (for all wheel drive) using same DC bus voltage. Additionally, the control of multi-output converter can distribute equal power between the two motors to improve the overall stability. The hardware prototype is developed in the laboratory to verify the operation of the proposed system and preliminary results are included in the paper.
