Abstract

Dodecagonal (12-sided polygon) voltage space vector structures have advantages like extension of linear modulation range, elimination of fifth and seventh harmonics in phase voltages and currents for the full modulation range including extreme 12-step operation, reduced device voltage ratings, lower switching frequency requirement making it more suitable for high power drive applications. A simple carrier based modulation method is proposed to obtain space vector pulse width modulation (SVPWM) switching patterns for a dodecagonal voltage space vector (SV) structure using only sampled reference voltages in this paper. The algorithm outputs the sector information and the SVPWM compare values which can be set as the references for any PWM module to obtain SVPWM switching sequences. The proposed method eliminates the need for partitioning and recombination of the computed timing values, angle estimation and computation of modulation index which in common in conventional SVPWM modulation technique. Simulation and experimental results are presented to validate the proposed method.
