As a rule of thumb, the switching frequency must be higher than the audio bandwidth to prevent audible noise. Additionally, it must not interfere with the L6564's minimum internal starter period (reported in the datasheet). On the...
Also, Type III can provide more potential for loop bandwidth and stability. Of course, to evaluate a system we should not only use the open-loop transfer function and the Bode plot, but we should also observe if the root locus of the closed-loop transfer function is in the left ha...
release 21.02, the XY plot in the Sweeper tool of LabOne enables you to draw Nyquist plots in parallel with Bode spectroscopy figures. The Nyquist plot can be configured freely, and its scales can be locked with the so-called 'track feature' to display the Nyquist plot in a true 1:1 ...
