Abstract	The invasive model of power supply for the commercial blood pumps has brought great discomfort to the patients. An inductive power transmission system based on transformer for blood pumps has been designed and developed. The system is mainly consist of power supply, control circuit of switch, transformer, rectifier circuit and energy storage element. Experiments on power transmission in the system have been conducted for evaluation impact of frequency of switch, gas gap and windings number on the transmission efficiency of the system. The experimental results demonstrate that frequency of switch, gas gap and windings number influence the transmission efficiency in the inductive power supply system. The transmission efficiency decreases with the increase of the gap in the transformer and the system with the gap of 1 mm has the highest efficiency in the same performance conditions. The relation between the efficiency and the frequency of switch or the secondary windings number seem to be an approximate normal distribution: the system with the secondary windings number of 60 has the maximal efficiency; when the frequency of switch is 40 kHz, the efficiency reaches the peak.
