Analysis of SVPWM with Minimum Switching Losses for Multi-Modular Converter

摘要: The classic voltage space vector PWM (SVPWM) is a kind of symmetrical regular-sampled with zero sequence component added to its modulating wave. technique carrier phase shifted SPWM (CPS-PWM), which combines the multilevel technique, characteristic high equivalent switching frequency output A named sample time staggered SVPWM CPS-PWM presented in this paper. In order reduce maximum current, into individual converter units can be adjusted dynamically according load current. Thus, non-switching sectors arranged close period So current each element reduced effectively and minimum losses multi-modular are achieved. Simulation results implemented by PSCAD/EMTDC show validity proposed approach.
