Abstract
Because of low energy transmission efficiency of the transcutaneous coupling power supply device, the factors affecting inefficiency are analyzed and an implantable stimulator external powered is designed. The circuit consists of High-frequency inverter module, transcutaneous transformer and an isolated pulse generator. The circuit realizes that the polarity, amplitude, frequency and pulse width of stimulating pulses are adjustable and controllable. The distance between two transcutaneous coupling coils is the thickness of human skin, usually 5~15mm. Through practical tests at a distance of 10mm, experimental results show that the maximum transmission efficiency is 7.66% at the high-frequency carrier of 300KHz. The variable range of amplitude is between 0 and 10 voltages. The range of frequency is between 100 and 300Hz. So the designed circuit meets the demand of implantable stimulators.
