Fenestration laminectomy of L3、5 and part of S1 was performed and the lower threshold dorsal rootlets of L2、3、5、S1 were selectively sectioned judging by electrical stimulation on the patients with lower extremities involved. Open-door laminaplasty of C5-7 and selective posterior rhizotomy of C5-8 were performed on 5 patients with upper limbs involved simultaneously in half a year. For 2 patients with lumbar stenosis or protrusion of intervertebral disc or unstable lumber, internal fixation of pedicle screw was performed while SPR.

针对下肢痉挛患者采用L3、L5及部分S1椎板开窗，通过电刺激测阈值法选择性切断部分L2、3、5，S1脊神经后根；5例合并上肢痉挛瘫患者半年后采用颈后C5~C7单开门法，选择性切断部分C5~C8脊神经后根。2例合并腰椎不稳定、椎管狭窄及腰椎间盘突出，则术中在行SPR的同时行椎管减压，突出椎间盘髓核摘除，并行经椎弓根内固定。

The thesis mainly researches on the single phase AC/AC converter in the topologies including AC_Buck and AC_Cuk. Firstly, the operating principles of the two converters are analyzed in detail and the rules of their parameters design are educed; The commutation of their power switches which is the key of these topologies to realize is analyzed in detail and a feasible solution which can be named RCD-Commutation mode is presented and proved effectual by theory analyses and simulation results.

本文首先分析了AC_Buck变换器的变换原理，得出了电路参数设计准则；继而对电路实现的难点即功率管换流问题进行了深入分析，并得出了一种可行的解决方案即RCD换流方案；作为对简单拓扑单相直接AC/AC变换器控制策略的探索，本文以AC_Buck为平台，对电压单闭环瞬时值控制方案进行了研究，在理论分析和仿真研究的基础上设计并制作了一台采用RCD换流、电压单闭环瞬时值控制的AC_Buck变换器原理样机。
