Contained within this paper is a discussion into the modelling and control of the electrical architecture for a HEV. Two configurations of electrical architecture are discussed; a system in which the bus voltage is allowed to vary during vehicle acceleration and regenerative braking and secondly, a fixed bus voltage system in which the voltage is held constant by the inclusion of a bi-direction...

Due to the high power density, inherent zero-voltage-switching (ZVS), and voltage-conversation ratio, current source-based isolated dual-active-bridge DAB–DC/DC converters are extensively used for charging EVs under constant-current mode. However, fast dynamic response of an output is a crucial requirement DC/DC operating as source. This study proposes controller (FCC) tracking desired various ...

This paper presents a current-fed full-bridge boost DC-AC-DC converter with transformer isolation operating without switching power dissipation. The output voltage is regulated by dc-ac converter whose frequency changes with a constant turn-off time of transistors. The proposed converter is devoid of parasitic oscillations, as all of the parasitic capacitances and inductances are included in a ...

The growing interest in the development of electric vehicle charging system based on expanding green car market is to meet the system demand for high efficiency and high density output characteristics.

A DSP-based self-adaptive proportional-integral (PI) controller to control a DC-DC converter is proposed in this paper. Full-bridge topology is adopted here to obtain higher power output capability and higher conversion efficiency. The converter adopts zero-voltage-switching (ZVS) technique to reduce conduction losses. A parallel secondary active clamp circuit is added to deal with voltage over...

In this paper, a DC-DC resonant converter with high voltage gain and small size is studied. To reduce the size and weight of this converter, the operating frequency should be as high as possible. In this research, the frequency changes from 120 to 200 kHz. Due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. Resonant converters are su...

This paper presents a method to control both the dc boost and the ac output voltage of Z-source inverter using neural network controllers. The capacitor voltage of Z-source network has been controlled linearly in order to improve the transient response of the dc boost control of the Z-source inverter. The peak value of the line to line ac output voltage is used to control and keep the ac output...
