Abstract
The present disclosure provides systems and related methods for reducing noise and interference in communications between an external device and implantable medical devices. The external device comprises an isolated switching power supply that includes a transformer separating a non-isolated side from an isolated side of the power supply. The transformer includes a primary winding on the non-isolated side, the primary winding extending between a primary winding upper end and a primary winding lower end, and a secondary winding on the isolated side, the secondary winding extending between a secondary winding upper end and a secondary winding lower end. The power supply further includes a high-frequency switch configured to selectively connect and disconnect the primary winding lower end to a ground, wherein the primary winding is electrically coupled to a supply voltage at an intermediate point between the primary winding upper end and the primary winding lower end.
