摘要

为了满足中子管离子源电源高效率小体积的要求，设计一种串联谐振推挽倍压变换器的技术方案。该变换器利用功率管寄生参数消除电路寄生振荡，利用倍压电容作为谐振元件实现开关管的ZVCS，降低损耗。研究中采用基波分析法建立电压增益数学模型，反映谐振品质因数对电压增益的影响，给出一种适用于推挽LC谐振倍压电路的参数设计方法，利用saber仿真并制作一台50W样机验证该变换器原理和理论分析的正确性。

Abstract:

In order to meet the high efficiency and small size of neutron tube ion source power supply, a technical solution of series resonant push-pull double voltage converter is designed. This converter utilizes the parasitic parameters of Metal-Oxide-Semiconductor Field-Effect Transistor(MOSFET) to eliminate the parasitic oscillation of the circuit, and uses the voltage doubler capacitor as the resonant element to realize the zero voltage current switching(ZVCS) of the switch to reduce the loss. The first wave analysis method was used to establish the voltage gain mathematical model to reflect the influence of the resonance quality factor on the voltage gain. A parameter design method suitable for a push-pull LC resonant voltage doubler circuit is given. A 50W prototype was simulated and manufactured using saber software to verify the correctness of the principle and theoretical analysis of the converter.

Key words: ZVCS push-pull topology series resonant voltage doubling rectifier switching power supply saber simulation
