Systems and methods for common-mode voltage reduction in AC drives |
摘要 |
Control systems, methods and power conversion systems (110) are presented for controlling common mode voltages in AC motor loads driven by inverter PWM control using switching sequences (162) 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, along with enhanced deadtime compensation and reflected wave reduction techniques in providing pulse width modulated switching signals (142b) to a switching inverter (110b). |
