This paper presents a simple space vector
approach for the generation of different switching sequences such
as Space Vector Pulse Width Modulation (SVPWM), Basic Bus
Clamping PWM (BBCPWM) and Advanced Bus Clamping
PWM (ABCPWM) algorithms with reduced complexity. It brings
out alikeness between the carrier comparison and space vector
approaches. The conventional space vector approach requires
calculation of sector and angle information which is a complex
procedure. For simplicity the proposed space vector approach
generates pulses using instantaneous phase voltages only. To
validate the proposed algorithm simulation studies have been
carried on vlf controlled induction motor drive at various
modulation indices and the results are presented. The results
show the good agreement with the proposed work.
