“…When the battery voltage rises to the set reference value, the charging current to the battery is reduced to 7–8 A since the control is switched to CV mode, as shown in test results. The ripple voltage allowed on the output of a stationary battery charger is specified by the NEMA (National Electrical Manufacturers Association) standard PE5 [31], based upon which the maximum limit of ripple current for a 100 Ah battery is given as 5 A [32]. For proposed EV charger, the appropriate design of DC‐link capacitor for reduced voltage ripple is achieved using (13), which further reduces the charging current ripple.…”

Conventional electric vehicle (EV) battery chargers suffer from severe power quality (PQ) issues at AC mains, due to non-linear nature of a diode-bridge rectifier, used for AC-DC conversion. Here, a power factor correction (PFC) circuit based on an isolated discontinuous conduction mode (DCM) zeta converter topology is designed and implemented for charging a 100 Ah, 48 V lead-acid EV battery. Test results, for charging an EV battery with constant current-constant voltage mode (CC-CV) control, are shown with a 1 kW zeta converter prototype. Test results show that the proposed zeta converter conforms to the improved PQ standard such as the IEC 61000-3-2, as well as, a unity power factor (UPF) input current with low harmonic distortion factor is achieved. Moreover, a smooth battery current is obtained during charging, even when there are fluctuations in the supply voltage hence enhanced lifetime of the battery is achieved.

“…Furthermore, this converter can present high input current ripple, which can damage the batteries of microgrids. 19 To improve the performance of the classical bidirectional DC-DC converter, the converter in Garcia et al 20 is presented. This converter can operate in asynchronous interleaved PWM strategy, which decrease the input current ripple and current stresses but shows a high-voltage stress in the switches.…”

SummaryIn this paper, a new bidirectional nonisolated DC‐DC (direct current–direct current) converter to interface microgrid energy storage systems is proposed. This converter is based on the classical bidirectional boost/buck converter, the most used converter in microgrids and can operate both in step‐down and step‐up modes. Besides that, this converter presents low number of components, low voltage and current stress on components, simplicity of operation, low current ripple from low‐side power supply, and two different modes of operation: synchronous and asynchronous. In addition, in this paper, the modeling, control, and power losses estimate of the proposed converter are carried out and the performance of the converter in different aspects of the microgrid application is evaluated, such as step load, abrupt power flux change, and transient analysis. A prototype of 1 kW, 144 to 400 V, is developed in the laboratory to validate the theoretical evaluations of the proposed converter. Besides that, the proposed converter is also evaluated under different dynamic condition which illustrates the effectiveness of the converter. Finally, the maximum efficiency obtained is 97.1% for 500 W working in step‐down operation.
