An evaluation of a parallel-resonant current-source converter for an electrothermal thruster
MetadataShow full item record
The Parallel-Resonant Current-Source Converter promises highly efficient DCDC power conversion. It uses zero-voltage switching to reduce the losses and improve the converter efficiency. The Parallel-Resonant Current-Source Converter has been developed from an idea of Dr. Ehsani from Texas A&M and Dr. Pitel from MagnaPower Electronics, Inc.. It is primarily intended for space applications, where efficiency, reliability and size are traditionally important. The reliability of the converter is increased by the current-source characteristics of the input and the minimum device count. The converter falls under the classification of resonant converters, which are gaining importance due to ever increasing demands on converter size and efficiency. Although wide application of resonant-mode converters is handicapped by the complexity in control when compared to PWM converters, they are perfectly suitable for some specific applications. Improvement in control and sensing devices will render resonant technology more attractive in the future.
