Multi-phase active rectifier |
摘要 |
A multi-phase active rectifier includes a plurality of active switching devices selectively controlled to convert a plurality of alternating current (AC) input voltages to a direct current (DC) output voltage. Control of the active switching devices is provided by a controller that includes an outer control loop for regulating the DC output voltage to a desired value, and an inner current loop for shaping the AC line current. The outer control loop compares the DC output to a threshold value to generate an error value, and multiples the error value with the plurality of monitored AC input voltages to generate modified AC input voltages. An inner control loop compares the modified AC input voltages with monitored AC line current values to generate a plurality of difference signals used to selectively control the plurality of active switching devices. |
