With the aid of Zemax software, a three-mirror, unobscured, high-resolution optical system with large aperture, long focal length was successfully aligned by first collecting interferograms from several fields of all image plane, and obtaining the wavefront error, namely, obtained wavefront Zernike polynomials; then using the self-made program package to calculate the optical system misalignment.

利用Zemax光学设计软件与自编计算机辅助装调软件，实现了对大口径、长焦距、无中心遮拦离轴三反射镜光学系统的装调。通过Zemax软件模拟光学系统的失调模式，得到整个光学系统的波前像差，把波前像差代入到自编的复杂光学系统计算机辅助装调软件中，计算出光学系统的失调量，与引入的失调量对比，证明了其正确性。在实际的装调过程中，用小型球面干涉仪分别收集3个视场的干涉图，得到失调光学系统的失调量，用Zemax软件验证失调量数据的正确性，从而指导装调。

In this paper, the basic principle and the power factor of conventional SERDS are discussed. Aiming at its shortage of low power factor, boost chopper type SERDS is adopted. The equivalent circuit of the new scheme is built up, and then vector diagram is used to analyze the power factor of the system, also the harmonic distortion of the system is discussed. The experiment device is established base on a 380F/7.5 kW induction motor and a passive soft switching scheme is applied in order to improve the working condition of IGBT. At last, the experimental results are shown.
