一种开关型高压直流电源的设计

A Design of High Voltage DC Power Source with High Frequency Rectification

提出一种脉宽调压式功率管－ＬＣ高压直流电源的电路设计。由脉宽调制［ＰＷＭ］电路输出方波脉冲驱动开关功率管－ＬＣ电路，使其产生高频功率振荡；通过调谐脉冲宽度控制输出高压；设计同步脉冲反馈电路，迫使驱动电路的脉冲频率与ＬＣ谐振同步，从而提高输出效率和脉宽调谐能力，实现大功率输出。

The thesis put forwards a design of electric circuits which can get high-power output of high voltage DC. The circuits include pulse width modulation(PWM)circuit,synchronization circuit,LC circuit and power switch transistors etc. The output of PWM pluses synchronized by feedback signals drive the transistors and LC circuit to get power pluses output.
