Abstract：With the fast development of power electronics, very high frequency (VHF) power converters (30~300MHz) have gradually become a research focus, which can greatly reduce the value and, volume of passive components and while improving the system power density. Traditional research mainly focuses on the parameter design of the inverter with fixed load, and the designed converter based on this method has high parameter sensitivity. However, the load of the inverter varies in a wide range in the actual scene, which poses challenges to the efficient operation of the VHF conversion system. In this paper, the resonant parameters and matching network of the wide load range VHF converter are summarized, and the parameter design methods of the VHF power converter are introduced and compared. Meanwhile, the impedance conversion and compression network structure suitable for the VHF power converter are discussed and analyzed, which can provide a reference for further research of on the highly efficiency efficient operation of the VHF converter.
