碩士 === 國立臺灣大學 === 機械工程學研究所 === 89 === The purposes of this thesis are to study and implement a full-bridge phase-shifted zero voltage switching ( FB-PS-ZVS ) power converter with current mode control. The distinguishing features of this thesis are to combine the ZVS operation with current-mode control. Their small-signal models are also studies and derived. There are many poor performances in conventional switching power supply have been improved. These disadvantages include weight, volume, power density, performance of transient response, power losses, EMI/RFI problems etc. By the raising of switching frequency, most of the disadvantages have been advanced. By combining the current-programmed control, many problems in charger design such as charging current equalization, charging capacity, the stabilization of charging conditions, the dynamics response of charging voltage/current can be much improved.
