The fast development of electric vehicles (EVs) provides significant opportunities to further utilize clean energies in the automotive. On-board chargers (OBCs) are widely used in EVs because of their simple installation and low cost. Limited space in the vehicle and short charging time require an OBC to be power-dense and highly efficient. Moreover, the possibility for EVs to deliver power back to the grid has increased the interest in bidirectional power flow solutions in the automotive market. This paper presents a comprehensive overview and investigation on the state-of-the-art solutions of bidirectional OBCs. It reviews the current status, including architectures and configurations, smart operation modes, industry standards, major components, and commercially available products. A detailed overview of the promising topologies for bidirectional OBCs, including two-stage and single-stage structures, is provided. Future trends and challenges for topologies, wide bandgap technologies, thermal management, system integration, and wireless charging systems are also discussed in this paper.

“…Thus, the maximum energy stored in the TCM ZVS inductors is 9.23 mJ; by contrast, the ZVS inductors for QCM only process a maximum energy of 0.8 mJ. Since the volume and power loss of an inductor is proportional to the maximum energy storage [45], [46], the ZVS inductors for QCM can be of much lower power loss and smaller size than the TCM solution.…”

This paper proposes a generic zero-voltage switching (ZVS) scheme for parallel power MOSFETs. Uncoupled or inversely-coupled differential-mode (DM) commutation inductors are added to the midpoints (AC terminals) of parallel MOSFET half-bridges (HBs), and a time-delay-based control scheme is applied, generating a circulating current flowing through these commutation inductors. Thus, the inductor currents are reshaped as quadrilaterals, which enable all the parallel transistors to achieve ZVS. The mode of operation of the proposed paralleling technique is entitled quadrilateral current mode (QCM) due to the quadrilateral-shaped commutation inductor currents. The operating principle of the QCM-paralleling technique is detailed mathematically, yielding accurate closed-form analytical expressions for modulation parameters. Finally, simulations and experimental results of a QCM-enabled synchronous Buck dc-dc converter are presented to validate the theoretical considerations. Index Terms-Parallel power MOSFETs, zero-voltage switching (ZVS), quadrilateral current mode (QCM)

“…T HE requirements for high efficiency over full operation range have become stricter in applications such as electric vehicles [1], wind power generation [2], more electric aircraft, etc. In the search for new approaches, the adoption of switching building blocks formed by an active switch and diode pair is an industry preferred solution and lies as the foundation of classical topologies like Buck dc-dc, Boost dcdc, and bridgeless PFC converters [3].…”

This paper proposes a positively-coupled-inductor (PCI) based paralleling scheme for basic semi-bridge switching cells which are formed by power MOSFETs and diodes. Both the semi-bridge switching cells and the inductors are split into two parallel parts, and thus, a small differential-mode inductance is formed between the midpoints of the parallel semi-bridge switching cells. A time-delay-based modulation strategy is applied to generate a controllable circulating current which enables all active switches to achieve the zero-current switching (ZCS) or zero-voltage switching (ZVS), and all diodes to achieve ZCS turn-off. Accordingly, the switching loss and the reverse-recovery loss can be significantly reduced. The operating principle of the proposed paralleling scheme is characterized by two complementary operation modes: desynchronized mode with soft-switching (lower switching loss) and synchronized mode with lower conduction loss. Compared with conventional soft-switching schemes, this solution features zero auxiliary switches, constant switching frequency, and improved full-power-range efficiency enabled by the dual operation modes. Furthermore, design guidelines of the PCI are presented where a novel winding arrangement is proposed and verified to obtain a controllable differential mode (DM) inductance. The operation principles and advantages of the proposed paralleling structure are comprehensively validated on both Buck and Boost dc-dc converters with Si/SiC power MOSFETs and diodes. Index Terms-Parallel MOSFETs, zero-voltage switching (ZVS), zero-current switching (ZCS), dual operation modes.
