It uses a simple switching scheme to energize and de-energize the three phase windings of the SRM.</p><p>The switches are controlled by 3 index sensors that align the windings' activation and de-activation at the desired rotor angle. Note that when de-energizing a winding and the switches are opened, the current continues to flow from ground to the battery connection, via the diodes, thus returning energy stored in the winding inductance back to the supply. Once that current reaches 0.0 A, the now reverse biased diodes prevent a current reversal and re-energizing of the winding.</p> About text formats Tags Select a tag from the list or create your own.Drag to re-order taxonomy terms.
