180nm HVIC technology for digital AC/DC power conversion

2017 29th International Symposium on Power Semiconductor Devices and IC's (ISPSD), 2017
A new high-voltage integrated circuit (HVIC) technology has been developed and optimized for AC/DC power conversion applications that require increased digital content. This cost-effective process uses 3.3V CMOS and a 180nm backend process to provide about 10X greater digital circuit density compared to conventional 0.5um 5V CMOS solutions.

A Direct Power Conversion Topology for Grid Integration of Hybrid AC/DC Energy Resources

IEEE Transactions on Industrial Electronics, 2013
This paper proposes a multiple-input versatile matrix converter (VMC) for integrating hybrid ac/dc energy resources and storages to the power grid. The VMC is developed from the traditional indirect matrix converter but operates in the reverse-boost mode rather than in the forward-buck mode.

A novel AC-DC Converter un-requiring inductors for power conversion

2008 Twenty-Third Annual IEEE Applied Power Electronics Conference and Exposition, 2008
A new ac-dc converter is proposed and its experimental results are also presented. This AC- DC converter does not require any inductor and any high voltage capacitor in input rectification. It also shows very low stand-by power consumption compared to conventional switching mode power supply (SMPS) ac-dc converters while it reveals a drawback in ...

Thermal wattmeter with direct AC/DC power conversion

Proceedings of Conference on Precision Electromagnetic Measurements Digest, 2002
A thermal wattmeter with direct AC power to DC voltage conversion is described. A three-terminal thermoconverter (TTTC) is used for AC/DC power substitution. The TTTC enables simultaneous application of mutually independent current and voltage into the same heater and this way to force phantom power dissipation in this heater.

Simplified Analysis and Design of an AC/DC Power Conversion System for Traction Drives

IEEE Transactions on Industry Applications, 1981
An ac/dc power conversion system suitable for traction drives supplied by an ac feeder line is considered. In order to work out a simple procedure for the preliminary design of the conversion system, some simplifying hypotheses are made. These hypotheses allow a simple analysis of the overall steady-state behavior of the power conversion system.

A direct power conversion topology for grid integrations of hybrid AC/DC resources

Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012
This paper proposes a multiple-input versatile matrix converter (VMC) to integrate hybrid ac/dc energy resources and storages to a power grid. The VMC is developed based on the indirect matrix converter (IMC) with its six-switch voltage source converter replaced by a nine-switch topology.
