碩士 === 大同工學院 === 電機工程研究所 === 81 === In this thesis, a half-bridge series-parallel resonant converter with and without postregulators is investigated for discontinuous conduction mode operation. The compre- hensive analysis of the SPRC is presented. The SPRC is superior to the pure series and pure parallel converters by removing their main disadvantages and taking on the desirable characteristics. The SPRC with a magnetic amplifier, which blocks the rising edge of the secondary voltage, can undergo analysis Modified topological modes and steady-state analysis are proposed. According to the steady-state analysis, the selection of resonant components is derived and the computer simulation is given in the normalization system. The experiment results show that SPRC with postregulators has good cross-regulation. A 100KHz SPRC with magamp post-regulators is designed to compare with SPRC.
