Investigation of Transformer Winding Architectures for High-Voltage (2.5 kV) Capacitor Charging and Discharging Applications
TL;DR: In this article, the authors present analytical expressions for calculating leakage inductance, self-capacitance, and ac resistance in transformer winding architectures, ranging from the common noninterleaved primary/secondary winding architecture, to an interleaved, sectionalized, and bank winded architecture.
Journal ArticleDOI
Digital Control of a High-Voltage (2.5 kV) Bidirectional DC--DC Flyback Converter for Driving a Capacitive Incremental Actuator
TL;DR: In this paper, the authors presented a digital control technique to achieve valley switching in a bidirectional flyback converter used to drive a dielectric electroactive polymer-based capacitive incremental actuator.
Proceedings ArticleDOI
High voltage Bi-directional flyback converter for capacitive actuator
TL;DR: In this article, a high voltage DC-DC converter topology for bi-directional energy transfer between a low voltage DC source and a high-voltage capacitive load is presented.
Journal ArticleDOI
Efficiency Optimization by Considering the High-Voltage Flyback Transformer Parasitics Using an Automatic Winding Layout Technique
Prasanth Thummala,Henrik Schneider,Zhe Zhang,Ziwei Ouyang,Arnold Knott,Michael A. E. Andersen +5 more
TL;DR: In this article, the authors presented an efficiency optimization approach for a high-voltage bidirectional flyback dc-dc converter, which optimized the converter for driving a capacitive actuator, which must be charged and discharged from 0-V to 2.5-kV dc and vice versa, supplied from a 24 V dc supply.
Journal ArticleDOI
A 10-MHz GaNFET-Based-Isolated High Step-Down DC–DC Converter: Design and Magnetics Investigation
TL;DR: In this article, an isolated high-step-down dc-dc converter based on a class-DE power stage, operating at a 10-MHz switching frequency using enhancement-mode gallium nitride transistors, is presented.
