Bidirectional power convertor for voltage fed inverter machine drives

PESC `92 Record. 23rd Annual IEEE Power Electronics Specialists Conference, 2003
The authors describe the development and operational characteristics of a prototype bidirectional AC-DC power converter based on a novel topology, suitable for feeding the DC link of voltage-fed inverter drives. The circuit uses fewer components than proposed alternatives and exhibits significantly less supply current distortion than the conventional ...

Modeling average current mode control [of power convertors]

APEC 2000. Fifteenth Annual IEEE Applied Power Electronics Conference and Exposition (Cat. No.00CH37058), 2002
An averaged small signal model is presented which predicts some of the previously reported phenomena and offers new insights with analytical expressions useful for design. Detailed analysis is given for the buck converter topology with the boost and buck-boost results also provided.

A new optimal programmed PWM technique [for power convertors]

Proceedings of Second International Conference on Power Electronics and Drive Systems, 2002
The paper presents a new method-optimal programmed PWM (OPPWM) technique-which further reduces the harmonic distortion (THD) of the surplus power converter harmonics than those of conventional programmed PWM (PPWM) techniques and ameliorates the amplitude frequency spectrum distribution of the surplus harmonics. The scheme not only inherits many merits

Investigation of asymmetrical phase-shifted full bridge [power convertors]

Proceedings of IECON '95 - 21st Annual Conference on IEEE Industrial Electronics, 2002
In comparison to forward power converters, bridge topologies make use of parasitic components for resonant transition without the need of additional clamping circuitry. Thus, they are privileged in building high frequency high power converters, even if high efficiency is required.

Optimization of power of alkali metal thermo electric convertor

Journal of Power Sources, 2015
Abstract Alkali Metal Thermo Electric Convertor (AMTEC) uses infrared radiation to knock out electrons from some alkali metal acting as the working material. In the present paper sodium is chosen as the alkali metal. The freed electrons after going through a circuit and having done the prescribed work meet the sodium ions. A solid electrolyte, called

A new series of smart controllers (for power convertors)

Conference Record of the IEEE Industry Applications Society Annual Meeting, 2003
A series of three intelligent power integrated modules for 0.4 to 1.5 kW AC-DC-AC inverted power conversion has been developed. Each of these is fabricated in one common and compact housing to produce a three-phase converter, a three-phase inverter using insulated-gate bipolar transistors, opto-couplers for input-to-output signal interfaces, and ...
