So this paper selects national debts as our studying objects. By using principal component analysis method to study the zero coupon yield curve, we find that the movement of the curve yield can be simulated by two factors mostly, that is parallel shift and rotation. Then we quantitative them and get "synthetic parallel shift" and "synthetic rotation".

The main purpose of this thesis is to research and develop three different kinds of battery chargers of resonant-switch converters. Starting with the zero voltage switch and the zero current switch converters, which employ the quasi-resonant converter technique, we gain the best parameters of the resonance components from the characteristic curve diagrams of these two converters. Then we design battery chargers based on these two structures and use them to experiment on lead-acid batteries.
