This paper proposes a single-phase bidirectional AC/DC converter topology applied in V2G systems, which consists of an inverter and a bidirectional non-inverting buck-boost converter. This topology can operate in four modes: buck charging, boost charging, buck discharging and boost discharging with high input current quality and unity input power factor. The inverter switches at line frequency, which is different from conventional voltage source inverters. A bidirectional buck-boost converter is utilized to adapt to a wider charging voltage range. The modulation and control strategy is introduced in detail, and the switching patterns are optimized to reduce the current ripple. In addition, the semiconductor losses are analyzed. Simulation and experimental results demonstrate the validity and effectiveness of the proposed topology.

“…Harnessing the energy stored in these vehicles and providing ancillary services to the power grid is termed Vehicle-to-grid (V2G) [2]. A fleet of PHEVs and EVs can be used as a distributed energy source [3] and supply or sink reactive power or source real power under peak load conditions [4]- [6]. PHEVs and EVs will need an onboard charger with bidirectional capability in order to implement V2G.…”

Electric vehicles can provide a viable network of distributed energy storage and provide ancillary services to the grid, (Vehicle-to-Grid, V2G), but Electric Vehicle chargers need to be bidirectional in order to provide power back to the grid. In this paper, dq current control is proposed using a novel bidirectional, isolated, single stage AC-DC converter. Unity open loop power factor has been achieved in previous work using the novel topology but relies on a non-distorted voltage waveform to achieve unity power factor and lacks control of reactive power. The single phase input filter equations are transformed into the rotating dq reference frame by generating an imaginary beta axis. The filter dynamics are analyzed and controllers are designed for dq input currents. A phase shift component is added to the modulation scheme allowing control of the phase and magnitude of the converters input current. The topology and control scheme is simulated in PLECS. Simulation results are presented for various operating points and validate the theoretical analysis. The proposed control strategy implements real and reactive power control which is essential for V2G applications and the topology has the advantages of high switching frequency, isolation, voltage matching, high power density, and reduced size compared to the conventional cascaded isolated AC-DC topologies.

“…The 2-legged configuration popularity is due to low component count and simplicity. When a three phase connection is needed, a 3-legged HB with anti-parallel diodes is most prominently proposed [14,15,16,17,18]. It possesses the same advantageous of a 2-legged HB, but for a three phase system.…”

“…Otherwise HB converter cannot be used for the DC-DC subsystem. The dual active bridge and such based topologies are utilized in literature [12,14]. The topologies contain a HF transformer for galvanic isolation, but need at least 8 semiconductor switches to operate.…”
