A method for generating secondary-referenced control power (power convertors)

[Proceedings] APEC '92 Seventh Annual Applied Power Electronics Conference and Exposition, 2003
A method is described that uses a startup oscillator and the principal power components to generate a secondary-referenced voltage for the control circuit of an isolated power converter. The method eliminates the need for a separate housekeeping power supply in these converters.

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 ...

Modified switched power convertor with zero ripple

Proceedings of the 32nd Midwest Symposium on Circuits and Systems, 2003
A modified power conversion scheme suitable for switched mode converters which addresses the problem of output ripple without incurring an appreciable loss of efficiency is presented. An analog controlled current source is used to inject a current into the load which is equal and opposite to the ripple current due to the switching circuit.

New current regulation principle [for power convertors]

IEMDC 2001. IEEE International Electric Machines and Drives Conference (Cat. No.01EX485), 2002
In this paper, two novel methods for current regulation are presented. They both are based on the synchronized on-off principle, where an additional algorithm for null voltage vector is implemented, depending on the predicted current error at the end of the sampling interval. The methods are intended for use on modern DSP controllers.

Generalised convertor models for iterative harmonic analysis in power systems

IEE Proceedings - Generation, Transmission and Distribution, 1994
There is an increasing interest in steady-state analysis of electric power systems with convertors. Harmonic analysis can be performed in the frequency domain with iterative methods that are comprehensive and efficient but may present convergence problems; this drawback can be overcome by employing appropriate models of convertors.

Analysis of a stirling-cycle power convertor for domestic combined heat and power

IEEE 2011 EnergyTech, 2011
Use of a Stirling-cycle convertor is analyzed with respect to domestic application to micro Combined Heat and Power. An engine that can convert heat into electric power has the potential to extract more availability from fuel consumption than combustion for space heating alone.

Power transistor convertor with new, fast response regulator

IFAC Proceedings Volumes, 1974
Summary The paper describes the theory, design and practical performance of a power transistor converter with an output of o V to ±240 V and up to ±10 A, that is, up to 2.4 kW dc. The transistors are bridge connected and employ pulse-width modulation (PWM) with carrier frequency cancellation.
