Abstract：

DSP　(XC2267)　is　the　main　control　chip　which　does　the　increment　PI　algorithms　and　realizes　the　voltage　and　current　double　closed-loop.　Three-phase　thyristor　rectifier　method　based　on　the　phase　self-adjusting　of　FPGA　is　proposed.　A　method　for　swept-frequency　start　circuit　is　designed　to　implement　the　transition　between　the　high-power　and　low-power.　The　invert　system　uses　the　compound　control　of　improved　PWM　and　frequency　phase　lock　to　improve　the　control　accuracy　and　efficiency.　Lastly,　by　using　bench,　the　circuit　is　tested　and　the　feasibility　and　effectiveness　of　the　whole　system　are　verified.　©　(2014)　Trans　Tech　Publications,　Switzerland.
