“…A single-phase multilevel converters, such as three-level NPC [88], T-type [89] and six-level flying capacitor topology [90]- [94], enable device voltage stress reductions and power level increase. In addition to single-phase PFC topologies, a lot of research is being undertaken on three-phase bidirectional PFC converters like the full-bridge converter [95], NPC [93], T-type [96] and matrix converter [97]- [99]. Three-phase topologies can discharge power from the battery to the grid to achieve V2G.…”

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.

“…). But as discussed in [5], [20], [21], for ensuring a high modulation index and avoiding the over modulation, the unbalanced power provided by is quite limited, which makes the NPC VSC only possible to handle the imbalance of dc-bus capacitors, but unfit for the bipolar operation with unbalanced dc loads, unless a forth bridge is added.…”

A new three-phase active rectifier topology is proposed for bipolar dc distribution, which can achieve the independent dc-pole control, with only one two-level voltage source converter and an ac-side grounding inductor. The averaged large-signal model and linearized small-signal model of the rectifier are derived in the stationary reference frame. Moreover, a control system is proposed with proper controller parameters. Besides, the rectifier is tested on an experiment platform. Comprehensive experiment results are given and analyzed to validate the function of the proposed rectifier under different operation conditions, including the rectifier start-up performance, rectifier dynamics with unbalanced dc loads for two poles, and rectifier dynamics with asymmetrical dc voltages for two poles. Finally, the proposed rectifier is compared with other two existing ac-dc conversion approaches, in terms of required number and rating of components as well as power losses with different load imbalance levels, which further highlight some potential benefits of the proposed topology.

“…It separates the DC grid from the AC grid by removing the gate pulses when a fault occurs in the AC grid. The reference voltage is applied to the voltage controller to maintain the DC grid voltage constant, and the reference current generated here is compared with the actual current of the system via the current controller thereby generating 3-phase PWM gate pulse [14,15].…”

This paper proposes a half-bridge voltage balancer with a new controller for bipolar DC distribution systems. The proposed control scheme consists of two cascaded Proportional Integral (PI) controls rather than one PI control for balancing the pole voltage. In order to confirm the excellence of voltage balancing performance, a typical bipolar DC distribution system including a half-bridge voltage balancer with proposed controller was analyzed by computer simulations. Experiments with a scaled prototype were also carried out to confirm the simulation results. The half-bridge voltage balancer with proposed controller shows better performance than the half-bridge voltage balancer with one PI control for balancing the pole voltage.
