Summary: | 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.
