Abstract: The continuous flow circuit used in single-phase DC brushless motor drive system was studied. Compared with different kinds of drive system and ways of continuous flow based on the characteristics of small fan, the result of simulation and experiment showd that continuous flow circuit with a capacitor in non-bridge drive system could make the voltage lower and level shift faster in the period of phase changing.Non-bridge drive scheme is suitable for small fan because of its simple structure and reliable performance.

Key words: non-bridge driving system, continuous flow, fan driving
