中文摘要：
为实现多模块大功率高压电源均流并联扩容技术，用固定相对相位偏移的脉冲频率调制法，将多个高压大功率串联谐振逆变模块并联；并通过优化控制补偿网络设计及合理接地设计，解决并联系统自激和高压打火损坏控制电路难题。实验表明用该法实现高压电源的模块化并联扩容，简单可靠且并联模块越多电源纹波水平越小；无需内置电流控制环，模块间也能得到满意的均流效果；在脉冲负载和电阻负载条件下，均具有好的动态特性。
英文摘要：
A kind of current share parallel enlarged power technique for the multi-modular large-power high-voltage power supply was given. More series-resonant large-power high-voltage modules were operated through the pulse frequency modulator with a constant relative phase shift. The control system of the constant relative phase shift and the compensate net were discussed in detail, The problem of the system self-excitation and the effect of strike fire at high voltage were resolved. The results show： The parallel enlarged power of Multi-modular is feasible in this way; This technique is simple and reliable and the output voltage ripple is less with the more paralleled modules; The satisfied result of the current share can be achieved without inside current control loop; A faster system response is acquired in the conditions of pulse load and resistor load.
