Abstract
A high voltage resonant step-up convertor converts a lower voltage signal to a higher voltage signal. The converter may be used, for example, to supply power via electromagnetic coupling to an implantable medical device. In some embodiments, a power converter comprises a driver circuit and a resonant circuit. The resonant circuit generates a high voltage output signal at a selected frequency. The driver circuit is controlled by a low voltage signal and periodically generates a higher frequency signal (e.g., approximately twice the selected frequency) to drive the resonant circuit. In some embodiments, the driver circuit comprises another resonant circuit and a switching circuit. The switching circuit periodically pumps current to the other resonant circuit and isolates the two resonant circuits. The other resonant circuit periodically pumps current to the output resonant circuit.
