Isolated and soft-switched power converter

Patent Peng, Fang Zheng ; Adams, Donald Joe

An isolated and soft-switched power converter is used for DC/DC and DC/DC/AC power conversion. The power converter includes two resonant tank circuits coupled back-to-back through an isolation transformer. Each resonant tank circuit includes a pair of resonant capacitors connected in series as a resonant leg, a pair of tank capacitors connected in series as a tank leg, and a pair of switching devices with anti-parallel clamping diodes coupled in series as resonant switches and clamping devices for the resonant leg. The power converter is well suited for DC/DC and DC/DC/AC power conversion applications in which high-voltage isolation, DC to DCmore »« less

Discrete pulse control of AC/DC/AC converters for minimizing reactive elements

Miscellaneous Habetler, T.G.

Three phase ac/dc/ac converters operating with reduced reactive elements have been investigated in this work. It has been determined that the voltage sourced converter circuit topology results in a lower reactive element cost than a current sourced converter, independent of the switching strategy. With the topology fixed, further reductions in reactive element requirements must be accomplished through switch modulation. For any realistic modulation strategy, filter requirements are proportional to the switching frequency. Discrete pulse switching used in soft-switched resonant converters allows for much higher switching frequencies than conventional converters. All the concepts developed for control of reduced link converters aremore »« less
A soft switched direct frequency changer

Conference Villaca, M.V.M. ; Perin, A.J.

Recent development in power semiconductors and commutation techniques has brought back the interest in direct frequency changers. A soft switched three-phase to single-phase direct frequency changer is introduced adopting the bidirectional ZVS cell. Hence, the proposed converter does not need dead time between gate signals, presents natural protection against over current, uses a simple gate signal drive circuitry and the commutation losses are reduced with no increasing o the conduction losses. All types of ac modulation can be used and the bidirectional switches can operate in high frequency of commutation. A prototype assembled and the results obtained are discussed. Analysismore » and design are also presented.« less
Unified active and reactive power modulation of HVDC transmission systems. Final report

Technical Report Grund, C.E. ; Pohl, R.V.

In a study conducted by the General Electric Company for EPRI, the power modulation of a high-voltage direct-current (HVDC) system for stabilization of an ac/dc network was investigated. The use of both active and reactive power modulation (as opposed to only active modulation techniques) was studied. It was found that simultaneous modulation of both dc current and voltage was more effective than just current modulation by itself, since the dc voltage modulation could be used to minimize the reactive power changes resulting from a change of the dc current. This helps stabilize the ac busbar voltages at the converters, whichmore »« less
Auxiliary quasi-resonant dc tank electrical power converter

Patent Peng, Fang Z.

An auxiliary quasi-resonant dc tank (AQRDCT) power converter with fast current charging, voltage balancing (or charging), and voltage clamping circuits is provided for achieving soft-switched power conversion. The present invention is an improvement of the invention taught in U.S. Pat. No. 6,111,770, herein incorporated by reference. The present invention provides faster current charging to the resonant inductor, thus minimizing delay time of the pulse width modulation (PWM) due to the soft-switching process. The new AQRDCT converter includes three tank capacitors or power supplies to achieve the faster current charging and minimize the soft-switching time delay. The new AQRDCT converter furthermore »« less
