If
Maximum Switching Frequency
(05.018) has been set in the 2kHz to 6kHz range, setting
Low acoustic noise enable
(05.080) modifies the modulation
scheme to reduce the fundamental switching frequency acoustic noise.
When this mode is enabled, the effect of the switching frequency fundamental in the output voltage is reduced by moving the switching points of the output
phases in each PWM switching period by the same randomly weighted offset. This reduces the level of noise from the switching frequency but will introduce
noise at lower and higher frequencies at a lower audible level. The maximum offset reduces as the output voltage increases.
