摘要:
The disclosed invention varies the width of the energy pulses with constant frequency and constant amplitude to regulate the amount of energy transferred from an energy transmitting device placed outside a patient to an energy receiver inside the patient. The pulse width is achieved with a modulation technique, PWMT, to control the amount of energy transferred from the external energy transmitting coil in the system to the implanted receiver. The PWMT is used to digitally vary the amount of power from the power amplifier that drives the transmitting coil. Compared to previous analog systems a PWM system is a great deal more efficient and can easily be controlled from a digital domain system such as a microprocessor.
