“…This is achieved by improving converter technologies, integrating the charger with the converter, or integrating the charger with the drive motor. The first route is shown in the example in [21], which proposes a three-port DC-DC converter with power factor correction. The second route is presented in [22] which integrates a bi-directional AC-DC charger with a DC-DC converter.…”

 Abstract-Electric vehicles (EVs) and hybrid electric vehicles (HEVs) are the way forward for green transportation and for establishing a low-carbon economy. This paper presents a split converter-fed four-phase switched reluctance motor (SRM) drive to realize flexible integrated charging functions (DC and AC sources). The machine is featured with a central tapped winding node, eight stator slots and six rotor poles (8/6). In the driving mode, the developed topology has the same characteristics as the traditional asymmetric bridge topology but better fault tolerance. The proposed system supports battery energy balance and on-board DC and AC charging. When connecting with an AC power grid, the proposed topology has a merit of the multi-level converter; the charging current control can be achieved by the improved hysteresis control. The energy flow between the two batteries is balanced by the hysteresis control based on their state-of-charge (SoC) conditions. Simulation results in Matlab/Simulink and experiments on a 150 W prototype SRM validate the effectiveness of the proposed technologies, which may provide a solution to EV charging issues associated with significant infrastructure requirements.

“…A current trend is to develop high power on-board chargers to overcome range limitations [17] [18].

The first route is exampled in [19], which describes a three-port DC-DC converter with power factor correction.…”

“…However, the buck-boost topology generates more switching losses, because it requires two power switches to be switched during each PWM period t sw , thus providing a lower conversion efficiency. Therefore, other topologies like the SEPIC and the zeta topologies which use only one power switch were investigated (Aguilar, Canales, Arau, Sebastian, and Uceda 1997;Erickson and Maksimovic´2001;Marchesan, Dalla-Costa, Alonso, and do Prado 2007).…”

A novel CMOS integrated pulse-width modulation (PWM) control circuit allowing smooth transitions between conversion modes in full-bridge based bi-directional DC-DC converters operating at high switching frequencies is presented. The novel PWM control circuit is able to drive full-bridge based DC-DC converters performing step-down (i.e. buck) and step-up (i.e. boost) voltage conversion in both directions, thus allowing charging and discharging of the batteries in mobile systems. It provides smooth transitions between buck, buck-boost and boost modes. Additionally, the novel PWM control loop circuit uses a symmetrical triangular carrier, which overcomes the necessity of using an output phasing circuit previously required in PWM controllers based on sawtooth oscillators. The novel PWM control also enables to build bi-directional DC-DC converters operating at high switching frequencies (i.e. up to 10 MHz and above). Finally, the proposed PWM control circuit also allows the use of an average lossless inductor-current sensor for sensing the average load current even at very high switching frequencies. In this article, the proposed PWM control circuit is modelled and the integrated CMOS schematic is given. The corresponding theory is analysed and presented in detail. The circuit simulations realised in the Cadence Spectre software with a commercially available 0.18 mm mixed-signal CMOS technology from UMC are shown. The PWM control circuit was implemented in a monolithic integrated bi-directional CMOS DC-DC converter ASIC prototype. The fabricated prototype was tested experimentally and has shown performances in accordance with the theory.
