A High-Power-Density Power Factor Correction Front End Based on Seven-Level Flying Capacitor Multilevel Converter

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2019
This paper presents a power factor correction (PFC) front end based on a seven-level flying capacitor multilevel (FCML) boost converter. Compared to the conventional two-level boost converter, the proposed seven-level FCML converter features the use of ...

A Modular-Designed Three-Phase High-Efficiency High-Power-Density EV Battery Charger Using Dual/Triple-Phase-Shift Control

IEEE transactions on power electronics, 2018
In this paper, an enhancement-mode GaN high-electron mobility transistor (HEMT)-based 7.2-kW single-phase charger was built. Connecting three such single-phase modules to the three-phase grid, respectively, generates a three-phase ∼22-kW charger with the

High energy and high power density electrochemical capacitors

Journal of Power Sources, 1996
Abstract High energy density electrochemical capacitors were built with a newly discovered electrode material (amorphous RuO 2 · x H 2 O). Energy densities as high as 96 J/g (26 Wh/kg) were obtained based on the RuO 2 · x H 2 O electrode material alone. However, the power density of the capacitor is low.

High power density high voltage power supply based on AC-link

2015 54th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE), 2015
High power density is one of the developing directions of the high voltage converter. The converter based on AC-link has less energy conversion steps than the DC-link based; With the same switches, the transferred power capacity with continuous current mode of resonant circuit could be nearly 2 times than with the discontinuous mode, so converter based

Gearing Design for High Power Density

2020
High power density is one of the major attributes of gearing systems. It could primarily be achieved by adopting designs that feature multiple power paths, which make some of the gears multi-mesh gears, in particular the larger and heavier ones, and some of the pinions double-mesh ones.
