Matrix converters inherently have problems with commutation which are generally mitigated by using snubbers. Problem of commutation also places a limitation on their voltage transfer ratio. In this paper, a new high frequency linked AC-AC converter topology is proposed which ensures reliable commutation, taking care of parasitic inductances, with minimum snubber on the input side. A simple switching algorithm to achieve this is also suggested. The topology has the flexibility to improve the voltage transfer ratio of a conventional matrix converter while maintaining unity power factor on the input AC side. Simulation results support the feasibility of the scheme.
