An Isolated Three-Port Bidirectional DC-DC Converter With Decoupled Power Flow Management
TL;DR: In this article, an isolated three-port bidirectional dc-dc converter composed of three full-bridge cells and a high-frequency transformer is proposed, where phase shift control managing the power flow between the ports, utilization of the duty cycle control for optimizing the system behavior is discussed and the control laws ensuring the minimum overall system losses are studied.
Journal ArticleDOI
Power Electronic Traction Transformer—Medium Voltage Prototype
Chuanhong Zhao,Drazen Dujic,Akos Mester,Juergen K. Steinke,Michael Weiss,Silvia Lewdeni-Schmid,Toufann Chaudhuri,Philippe Stefanutti +7 more
TL;DR: Recently, the world's first ever power electronic traction transformer (PETT) for a 15-kV 16.7-Hz railway grid has been newly developed, commissioned, and installed on the test locomotive, where the PETT is presently in use.
Journal ArticleDOI
A PWM plus phase-shift control bidirectional DC-DC converter
TL;DR: In this article, a pulsewidth modulation (PWM) plus phase-shift control bidirectional dc-dc converter is proposed to reduce current stress and conduction losses, and to expand ZVS range.
Journal ArticleDOI
Power Electronic Traction Transformer-Low Voltage Prototype
Drazen Dujic,Chuanhong Zhao,Akos Mester,Juergen K. Steinke,Michael Weiss,Silvia Lewdeni-Schmid,Toufann Chaudhuri,Philippe Stefanutti +7 more
TL;DR: In this article, a lowvoltage (LV) PETT prototype is presented, which has been designed for the purposes of control hardware and software commissioning, thus serving a role of an analogue simulator.
Journal ArticleDOI
Full-order averaging modelling of zero-voltage-switching phase-shift bidirectional DC-DC converters
TL;DR: In this paper, a full-order small-signal modeling and dynamic analysis of zero-voltage-switching (ZVS) phase-shift bidirectional DC-DC converters is studied.
