Abstract
An implantable medical device charging apparatus includes a charging circuit. The charging circuit includes a series resonator responsive to a signal applied to the charging circuit. During operation, the series resonator inductively couples to a secondary coil within an implantable medical device to transfer energy to the secondary coil. The charging circuit also includes a parallel resonator coupled to the series resonator. The parallel resonator filters a first component of the signal from propagating to the series resonator.
