Application of single-phase to three-phase converter motor drive systems with IGBT dual module losses reduction

This paper aims to apply a universal filter configuration to supply a three-phase motor from the single-phase grid, in this case the motor must be supplied with the same frequency of grid. The initial hypothesis consider that is possible to minimize the converter's losses through the variation of motor voltage phase and through selection of an appropriate transformer. To reduce the IGBT dual module losses means to reduce the operational cost of the system. The initial investment of this configuration is very attractive for treating of a converter that works in shunt, in other words, only a part of the load power flows through the converter. Analysis in steady state has been realized, as well. Experimental results are showed to demonstrate the theoretical studied.
