Abstract

Provided are embodiments for a circuit (400) including a resolver (402) having a primary winding and a set of secondary windings, wherein the resolver has a resolver shaft, and a polarity detection circuit coupled to the resolver. The circuit can also include a synchronizer circuit coupled to the polarity detection circuit, wherein the synchronizer circuit synchronizes signals from the positive polarity detection circuit; and a controller configured to determine a direction of the resolver shaft using an output of the synchronizer circuit. Also provided are embodiments of a method for determining the resolver rotation direction using non-analog means.
