SYSTEMS AND METHODS FOR COMMON-MODE VOLTAGE REDUCTION IN FULLY REGENERATIVE AC DRIVES

摘要

Control systems, methods and fully regenerative power conversion systems are presented for mitigating common mode voltages in AC loads by employing inverter and/or active rectifier PWM control using switching sequences with only active vectors where a first vector of each switching sequence differs by one phase switching state from a last vector of a switching sequence of an adjacent sector.
