Abstract

The energy storage unit is one of the most important subsystems in the structure of hybrid electric vehicles since it directly impacts the performance, fuel economy, cost, and weight of the vehicle. New structures for the energy storage unit, which utilize both batteries and ultracapacitors, are widely under investigation. In order to fully utilize the advantages of each energy storage device, employment of multi-input power converters is inevitable. In this paper, two new double input converters are introduced. Their different operating modes are analyzed and their voltage transfer ratios are derived. Simulation results are used to verify the expected operational characteristics
