“…Other than the light load, it is also necessary to provide ZVS for a full load. Shao et al, (2017) proposed ZVS topology suitable for both light and full load conditions. It minimizes conduction losses in switches during a continuous conduction mode with the use of additional L and C components with a conventional buck converter.…”

DC–DC converters have wide applications in industries, motor drive circuits, electric vehicles, and power supplies. In traditional converters hard switching occurs due to switching losses. This imposes constraints on the converter’s efficiency which results in heat dissipation and reduction in the converter’s life. The proposed converter aims to encounter the hard switching problem with the provision of soft switching features. The presented topology is efficient with respect to the features of cost, compact size and durable lifetime of converter topology with the provision of low switching stresses. This research work proposes a novel stepdown converter with zero voltage switching characteristics. With the use of half bridge inverter switches and series resonant components in the auxiliary circuit, the target of zero voltage switching and reduction in switching stresses has been achieved. The proposed 500 W converter is designed to operate at frequency of 100 KHz with 300 V source input voltage. Output voltage of the converter is 150 V.

Hardware-in-the-loop simulation (HiLs) is an enabling technology for analysing and testing the control unit of highpower electronic system. However, the main difficulty remains in the design of a HiLs platform for a control unit with a complex electronic system. With the attempt to improve this issue, this study presents the HiLs setup utilising the dSPACE simulator under the background of the auxiliary power system of the electric locomotive. A massive parallel implementation approach for modelling the auxiliary power system is proposed for the implementation on field programmable gate arrays (FPGAs). The proposed method exploits the large response time of the auxiliary model to: (i) decouple the complex system into independent subsystems , (ii) partition the AC machine model solution from the rest power electronic system using the FPGA/CPU co-mix structure, and (iii) adopt nanoseconds range simulation time step. The whole HIL system can be used to evaluate both the hardware and software performance of the physical auxiliary control unit. The real time simulation results under steady-state and transient conditions demonstrate modelling accuracy and provide detailed insight into the development of this electrical powertrain.
