Vehicle ergonomics is one of the most important objectives for automotive applications. Reducing the size and weight is a prime concern for mobility. A novel unified converter with battery integration is proposed as an alternative to the existing power train configuration for hybrid electric vehicles. The power train has three phase PWM rectifier at the output of the alternator with battery connected to the neutral of the induction generator stator. With the proposed topology, vehicle size and weight can be reduced considerably. The topology is analysed for its control and performance specifications. Simulation studies are carried out in MATLAB/SIMULINK and results are presented.

Renewable sources like solar photovoltaic (PV) are preferred to be operated at low voltages. This necessitates high voltage boosting when they have to be connected to the high voltage DC bus. Conventional DC-DC converters (eg. boost and buck-boost) offer high voltage gain at the cost of reduced efficiency. This paper proposes a novel method to integrate low voltage PV power to the high voltage DC bus using a simple boost converter. The analysis of the proposed topology and control strategies are discussed. Simulation studies are carried out in MATLAB/SIMULINK and results for the same are presented.
