This paper first examines and compares several methods for producing a variable speed drive for the permanent split-capacitor (PSC) induction motor. Conventional modulation methods are compared using phasor diagrams and then an improved modulation scheme using a boost converter and a three-phase drive is proposed. The derivation of the required excitation waveforms for any arbitrary PSC machine as a function of the turns ratio is presented in addition to an expression for determining the amountdoi:10.1109/ias.2000.882152 fatcat:cgj73sqyvzhllcikkvl2p6hpxe
