 Abstract.

 A new detection and compensation method for voltage sag is proposed. Dynamic voltage correction device(DVCD) is the most effective device to solve voltage sag. Based on the shortcomings of the traditional compensation strategy, the compensation characteristics of the compensation strategy are analyzed systematically. This paper proposes a new compensation method based on the traditional minimum energy compensation method, which uses different minimum energy methods for different sags, namely zero active power exchange and minimum energy exchange. Through Simulink to establish the simulation model of minimum energy method, and make simulation analysis. The simulation results show that the method can achieve the minimum output active power while ensuring the compensation effect, which proves the feasibility and effectiveness of the method. This method can make full use of energy storage of equipment and has high economic benefits.

Abstract

One of the main problems in electric vehicles is the volume of their electrical systems because their bulky components carry additional mass and high cost to the total system. On this topic, interleaving-phases and magnetic coupling techniques have been reported as effective methods for increasing the power density of the DC–DC converters that work between the storage unit and the motor inverter. In that sense, a volume assessment of these topologies would provide a better understanding of the problems to be faced when an electric power train is designed. In this paper, a volume modelling methodology is introduced with the purpose of comparing four different DC–DC converters: Single-Phase Boost, Two-Phase Interleaved with non-coupled inductors, Loosely Coupled Inductor (LCI), and Integrated Winding Coupled Inductor (IWCI). The analysis considers the volume of magnetic components, power devices (conventional and next-generation), cooling devices and capacitors. The methodology can be used as a part of an optimization procedure to minimize the volume of DC–DC converters. Conclusively, LCI and IWCI were found effective to miniaturize power converters with a power density of 8.4 W/cc and 9.66 W/cc, respectively. Moreover, a maximum efficiency of 98.04% and 97.61% was obtained for a 1kW LCI and IWCI prototypes, respectively.
