Journal ArticleDOI
Electric Vehicle Charging Station Using a Neutral Point Clamped Converter With Bipolar DC Bus
TL;DR: Simulation and experimental results are presented to validate the proposed charging station architecture and provide complementary balancing capabilities by the use of an additional NPC leg acting as a bidirectional dc-dc stage, simulating the minimal load condition and allowing the modulator to keep the control on the dc voltages under any load scenario.
Proceedings ArticleDOI
Cascaded H-bridge multilevel converter multistring topology for large scale photovoltaic systems
TL;DR: In this paper, a new medium voltage multilevel multistring configuration is introduced based on a three-phase cascaded H-bridge (CHB) converter and multiple string dc-dc converters.
Journal ArticleDOI
Effective Voltage Balance Control for Bipolar-DC-Bus-Fed EV Charging Station With Three-Level DC–DC Fast Charger
TL;DR: Through the proposed VBC coordination, the controllable balancing region is extended so that additional balancing circuits are eliminated and the quality of the grid-side currents is improved as the NPC converter has more freedom to control currents.
Journal ArticleDOI
Electric Vehicle Charging Station With an Energy Storage Stage for Split-DC Bus Voltage Balancing
Sebastian Rivera,Bin Wu +1 more
TL;DR: In this paper, the authors proposed a novel balancing approach for an electric vehicle bipolar dc charging station at the megawatt level, enabled by a grid-tied neutral-point-clamped converter.
Journal ArticleDOI
Comprehensive DC Power Balance Management in High-Power Three-Level DC–DC Converter for Electric Vehicle Fast Charging
TL;DR: In this paper, a comprehensive dc power balance management (PBM) in conjunction with high-power three-level dc-dc converter based fast charger is proposed to solve the unbalanced power problem in the bipolar dc bus.
