Conventional modulation strategies for matrix converters based on trigonometric transformations and space vector techniques have their voltage transfer capability limited at about 0.866 p.u. This leads to a derating of motor capability by 25% in the realization of variable frequency drives using off-the-shelf line-fed motors, or requires custom designed motors for operation at reduced voltage. In...
This paper demonstrates a method of using a matrix converter with reverse blocking IGBTs (RB-IGBTs) to drive a brushless DC (BLDC) motor with nonsinusoidal flux distribution. The output currents are nearly rectangular and the input currents are sinusoidal. Recently introduced RB-IGBT modules allow for an efficient implementation of the classical topology 18-switch matrix converter. The RB-IGBT modules...
The three phase boost rectifier is gradually emerging to be the choice of approach for improving power quality for high power motor drive applications. Although the topology of the converter, its application and control techniques have been known for decades, a systematic design oriented model has not been established in the literature. This paper presents the development of a design-oriented model...
