Development on high-power and high power density capacitor charging power supply

2014 17th International Symposium on Electromagnetic Launch Technology, 2014
This paper discussed the high-power and the miniaturization technology of capacitor charging power supply. The design and implementation of parallel operating high power density CCPS prototype with "peak current shifting control" was described. The single CCPS prototype output power is 35kW and the whole output power of parallel operating CCPS is 70kW.

Flexible, High Power Density, Wearable Thermoelectric Nanogenerator and Self-powered Temperature Sensor.

ACS Applied Materials and Interfaces, 2019
We propose a flexible and wearable thermoelectric nanogenerator (FTEG) made from Bi2Te3, which allows high voltage and output power density. The proposed FTEG works as a thermopile with the end-to-end connection of 126 thermoelectric legs, and which is ...

High-Density Avionic Power Supply

IEEE Transactions on Aerospace and Electronic Systems, 1980
Dramatic reductions in size and weight have been achieved in the area of signal and information processing. Power conditioning circuits have not kept pace, primarily due to the relatively slow proggress ress in the passive energy storage and transformation devices.

A high-power-density DC/DC converter for high-power distributed power systems

IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2004
This paper presents a zero-voltage-switching (ZVS) three-level DC/DC resonant converter for high-power distributed power systems. The paper first addresses the operation of the converter at a fixed frequency, which is achieved by applying phase-shift control between the primary and the secondary sides of the transformer.

SH3: high code density, low power

IEEE Micro, 1995
Hitachi's SH series microprocessors feature 32-bit RISC architecture with a 16-bit, fixed-length instruction set. We describe SH3, a pipelined implementation of the SH architecture with on-chip cache, MMU, and software-programmable power management.

Power Density Optimization in High Fidelity Power Drive

IEEE International Conference on Electric Machines and Drives, 2005., 2005
This paper analyzes factors determining power density in high current and high MVA power electronic converters & solid-state switches and recommends practical approaches to increase power density. For years increase in power density was the result of improvements in the power semiconductors density, which is the determining factor in medium power ...
