Abstract: | This article investigates alternative three-phase ASD topologies for integrated motor drives by discussing the hardware requirements and comparing their performance, size of magnetics, and efficiency, which in this case is important in order to determine their cooling requirements. It presents possible converter topologies for the next generation of integrated motor drives, which are arranged in three groups. The grid side performance is analyzed by simulations and their losses estimated. Three recommendations are made, while, for a general application ASD with sinusoidal input current, the choice is given by the price of four diodes against a RB-IGBT. |
