Power supply for multiphase motor providing recirculation compensation features and related methods
Abstract:
A power supply may include power generation circuits, each configured to drive a respective winding of a multiphase motor; converter circuits, each configured to generate a digital driving signal for a respective power generation circuit, and a memory configured to store a plurality of fast recirculation compensation values corresponding to combinations of the digital driving signals that would otherwise result in a fast recirculation condition. The power supply may also include a controller coupled to the memory and configured to determine when a given combination of the digital driving signals would otherwise result in a fast recirculation condition, and based upon the determination, substitute at least one corresponding fast recirculation compensation value for the given combination of the digital driving signals.
