Resonant Links: A New Family of Converter Topologies for Solid State Power Conversion

This paper summarizes recent development on the resonant link power conversion family of power converters. These converters utilize a high frequency link to introduce zero voltage or zero current intervals. By switching at the zero crossings of the voltage or current, the converter switch losses can be greatly reduced, permitting at least an order of magnitude increase in the converter switching frequency. The converters can synthesize nearly sinusoidal currents on both input and output converters and can also maintain unity fundamental power factor at the system input.
