我們實際製作一個由傳統E類反流器,和E類整流器組成的高頻高效率諧振
直流/直流轉換器.在固定切換頻率下,負載電阻可從無載到滿載間變化,在
整個負載範圍上,開關電晶體和整流二極體兩者,維持零電壓切換.在輸入
電壓12V時,輸出電壓可從3V到30V變化.在本篇論文中,我們以二種不同的
切換頻率,分別為25kHz及100kHz模擬,在得到相同結果前提下,可由提高切
換頻率,達成降低元件的數值(即提高切換頻率,縮小元件體積).最後藉由
PSpice模擬和實驗的結果與理論相印證.

In this thesis, we make a high-frequency high-efficiency
resonant DC/DC converter,Which is composed of a classical Class
E inverter and a Class Erectifier.The converter operates with
load resistance ranging from a full loadto infinity,while
maintaining Zero-Voltage switching for the transistor in the
inverter and the diode in the rectifier. The output voltage is
varied from 3Vto 30V at an input voltage of 12V.We take
simulation for two different switching frequencies which are
under thecases of 25 kHz and 100 kHz,respectively. In the
precondition to satisfy theresult, we can raise the switching
frequency for our achivement due to reducethe size of the
elements in advance.At last,we varify the theorem from the
simulating result of PSpice and the experimenal data.
