Abstract :
A DC-DC power converter which transfers 12-48 W of power (regulated output voltage 24 V) across a large, variable air gap (1-2 cm) has been designed. This power converter employs double resonance to compensate the large leakage inductance of the primary and secondary of the transcutaneous transformer. To maximize the effect of resonance, a constant frequency, duty cycle control method is used. The duty cycle control presents advantages over a frequency control in terms of increase in DC voltage gain and reduction of the primary current. The analysis and design procedure for the proposed scheme is presented and the performance result is simulated and verified experimentally
