“…However, there are still many challenges to be addressed in these complex electrical systems [13]. A clear example is the charging process of electric vehicle batteries, whose voltage is 48V, and requires high current levels to achieve a fast and complete state of charge [14][15][16][17]. The characteristics of rechargeable batteries have always been critical in the electric vehicle development [18][19][20][21].…”

The excessive use of fossil fuels has caused great concern due to modern environmental problems, particularly air pollution. The above situation demands that different areas of research aim at a sustainable movement to reduce CO2 emissions caused by non-renewable organic fuels. A solution to this problem is the use of Electric Vehicles (EV) for mass transportation of people. However, these systems require high-power DC/DC converters capable of handling high current levels and should feature high efficiencies to charge their batteries. For this application, a single-stage converter is not viable for these applications due to the high current stress in a switch, the low power density, and its low efficiency due to higher switching losses. One solution to this problem is Multiphase Converters, which offer high efficiency, high power density, and low current ripple on the battery side. However, these characteristics are affected by the current imbalance in the phases. This paper is focused on the study of the effects of the current imbalance in a Multiphase Buck Converter, used as an intermediate cover between a power supply and the battery of an EV. Analyzing the efficiency and thermal stress parameters in different scenarios of current balance and current imbalance in each phase.

A high-frequency isolated transformer integrated circuit configuration is proposed for an interlink converter for microgrid applications. The interlink converter is connected to a 3-phase AC grid and a DC microgrid. Further, a control algorithm for the proposed circuit configuration is discussed. Subsequently, a 12-kW prototype is built, and experimental results are provided to demonstrate the validity of the proposed circuit, wherein the efficiency for BES/AC conversion was improved by 3% compared with conventional circuits.
