“…To effectively use battery storage energy, the study of the use of batteries in emergency application for a laptop computer has been presented in [25,26]. The vehicle-to-grid (V2G)/grid-to-vehicle (G2V) operations have also gradually received attention [27][28][29]. Besides, there are specific battery energy storage systems (BESSs) being developed [30][31][32][33][34][35].…”

A switch-mode rectifier (SMR) can provide adjustable and well-regulated DC output voltage from the available AC source with good line drawn power quality. Depending on the input/output voltage transfer characteristics, the schematics, the operation quadrant, and control, SMRs possess many classifications and application. Typical potential application examples include grid powered motor drives, battery chargers, various power electronic facilities, micro-grids, and grid-connected battery energy storage system (BESS), etc. In micro-grids, the SMR can be employed as the AC generator-followed converter to yield better generating efficiency. The SMR operation of its grid-connected inverter let the grid-to-microgrid (G2M) operation be conductable in addition to the microgrid-to-grid (M2G) operation. As for the electric vehicle (EV), the bidirectional inverter can be arranged to perform G2V/V2G operations in idle case, wherein the SMR operation is made in G2V battery charging.To promote the application potential and improve the operation performance of SMRs, this article presents the operation controls and applications of SMRs in microgrid systems incorporating BESS and EV as supplemental facilities. First, the classifications, operation principle, and some key issues of SMRs are explored.Secondly, the configuration of the studied system is introduced. Third, the controls and operations of SMRs in micro-grid, wind generators, and grid-connected interface power converters are described. Then the ones in BESS (B2G/G2B) and EV are introduced. Finally, some conclusions and suggestions are given.

“…As generally recognized, the use of electric vehicles (EVs) [1][2][3][4][5][6][7][8][9] is effective in reducing the fossil energy consumption and carbon-dioxide emission. These goals will be more effectively achieved by using the EV as a movable energy storage device and performing its inter-connected operations to microgrid or utility grid [4][5][6][7][8][9].…”

This paper develops a battery/supercapacitor powered switched-reluctance motor (SRM) drive for electric vehicle (EV) propulsion. Its on-board integrated charger is formed using the embedded motor drive components. The boosted motor drive DC-link voltage is established by an interleaved DC/DC boost converter from the battery. The super-capacitor (SC) is interfaced to the DC-link via a DC/DC buck converter. And it is connected to the battery bank by a diode to assist the battery in acceleration and deceleration. Good driving and regenerative braking performances are achieved by proper control. In idle condition, the grid-to-vehicle (G2V) battery charging can be conducted by the formed on-board integrated charger with good line drawn power quality. The established charger consists of a full-bridge boost switch-mode rectifier (SMR) and a buck DC/DC converter based charger.

“…On the other hand, chargers should be able to adapt to output voltage with different type of EVs [13]. In this regard, for EV application, due to different level of battery pack and utility voltage, only the boost converter topology is not appropriate and using a step-up DC-DC converter at the output of three-phase or single-phase buck type converter is necessary [14,15]. Torque Sharing Function for ripple reduction is the best method for high performance SRM drives [16].…”

-In this paper, a zero torque control scheme adopting current sharing function (CSF) used in integrated Switched Reluctance Motor (SRM) drive with DC battery charger is proposed. The proposed control scheme is able to achieve the keeping position (KP), zero torque (ZT) and power factor correction (PFC) at the same time with a simple novel current sharing function algorithm. The proposed CSF makes the proper reference for each phase windings of SRM to satisfy the total charging current of the battery with zero torque output to hold still position with power factor correction, and the copper loss minimization during of battery charging is also achieved during this process. Based on these, CSFs can be used without any recalculation of the optimal current at every sampling time. In this proposed integrated battery charger system, the cost effective, volume and weight reduction and power enlargement is realized by function multiplexing of the motor winding and asymmetric SR converter. By using the phase winding as large inductors for charging process, and taking the asymmetric SR converter as an interleaved converter with boost mode operation, the EV can be charged effectively and successfully with minimum integral system. In this integral system, there is a position sliding mode controller used to overcome any uncertainty such as mutual inductance or DC offset current sensor. Power factor correction and voltage adaption are obtained with three-phase buck type converter (or current source rectifier) that is cascaded with conventional SRM, one for wide input and output voltage range. The practicability is validated by the simulation and experimental results by using a laboratory 3-hp SRM setup based on TI TMS320F28335 platform.
