RC Snubber Circuit of Large Gap Magnetic Driven System

摘要：

Based on the single chip microcomputer (SCM) control theory, the control circuit of magnetic driving system of axial flow blood pump is designed. For the easy damage of TIP 122, which is used as the power switch of control circuit, RC snubber circuit is designed by analysis and experiments. And then an optimal matching of the key parameters is obtained to solve the security problem of the TIP 122. The experimental results show that the RC snubber circuit can improve the reliability and stability of the driving system, and to provide an experimental foundation for the further studies.
