IET Power Electronics, 2016 This study presents a novel Z‐source matrix rectifier (ZSMR). To overcome the inherent disadvantage that the voltage transfer ratio for traditional matrix rectifier (MR) cannot be more than 0.866, a Z‐source network has been combined with the MR. The proposed rectifier realises a voltage‐boost function and the Z‐source network also serves as power ...
