This paper makes permanent magnet synchronous motors of small-power as objects, derives the design principle and approach of power circuit for AC servo systems. The topology structure and design process of important elements＇parameters are introduced in detail. Meanwhile. to realize the close-loop control of PMSM, the relevant detection circuits are designed to collect main signals, on which the protection circuits are setup. Moreover, a power supply solution based on switch power technology is presented to settle for the variety of DC power supply in the system. The practical results show that the power circuits followed the above principle have stable performance. complete function and high reliability.
