POWER TRANSFER IN A MEDICAL IMPLANT
First Claim
1. A medical implant comprising:
- a power source configured to generate a direct current (DC) signal; and
a first interface configured to convert the DC signal to an alternating current (AC) signal;
a DC power storage device;
a second interface configured to convert the AC signal received from the first interface via two interface connection lines to a DC signal, and configured to provide the DC signal to the power storage device via two storage connection lines, and wherein the second interface includes;
at least one switch disposed between the two module connection lines and the two storage connection lines; and
at least one switch controller configured to control the at least one switch to prevent the power storage device from being electrically connected to an opposite polarity of the power source.

Abstract
A medical implant comprising a power source configured to generate a direct current (DC) signal, a first interface configured to convert the DC signal to an alternating current (AC) signal; and a DC power storage device. The implant also comprises a second interface configured to convert the AC signal received from the first interface via two interface connection lines to a DC signal, and configured to provide the DC signal to the power storage device via two storage connection lines, and wherein the second interface includes: at least one switch disposed between the two module connection lines and the two storage connection lines; and at least one switch controller configured to control the at least one switch to prevent the power storage device from being electrically connected to an opposite polarity of the power source.

9. An internal component of a medical implant system comprising:
-
a DC power source; and a DC/AC converter adapted to convert a DC signal from the power source to an AC signal; a DC power storage device; and a circuit connected to the DC/AC converter via two interface connection lines, and connected to the power storage device by two storage lines, wherein the circuit is configured to convert the AC signal and a DC signal, the circuit comprising; at least one switch disposed between the two module connection lines and the two storage connection lines; and at least one switch controller for controlling the at least one switch such to prevent the power storage device from being electrically connected to an opposite polarity of the power source. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for transferring power from a power source to a power storage device of a medical implant, comprising:
-
converting, with a first interface, a direct current (DC) signal from the power source into an alternating current (AC) signal; providing the AC signal to a second interface via two interface connection lines; converting, with the second interface, the AC signal to a DC signal for deliver to a power storage device via two storage connection lines, wherein the second interface comprises at least one switch disposed between the interface connection lines and the storage connection lines; and causing the at least one switch to open and close such that at no time is one of the output lines electrically connected to one of the input lines of opposite polarity. - View Dependent Claims (18, 19, 20)
