Abstract :
The features of a three-phase resonant-commutation based variable-frequency converter applicable in a variety of industrial applications are presented. Minimization of switching losses as accomplished by resonant commutation of the converter is highlighted. Design and development of the DSP based controller is described. Strategies developed for switching of converter devices in relation to the resonant-commutated link are discussed. Results from Pspice simulation studies of the converter are presented. Experimental results while the single-phase laboratory model of the converter supplied passive loads are given and observations summarized
