【摘要】：提出一種控制模式,構(gòu)造了一種基于Boost變換器的雙極性高壓雙快沿脈沖源,形成雙極性高壓脈沖的原理是利用兩組Boost變換器,通過對(duì)稱控制在負(fù)載上輸出交替變化的電位。由于二極管轉(zhuǎn)換速度比有源功率開關(guān)管快,因此輸出脈沖前沿比后沿陡峭,前沿時(shí)間約為40 as,而后沿時(shí)間約為160 ns。輸出脈沖頂部平坦,約為350 ns。脈沖源工作于不連續(xù)模式,實(shí)測(cè)升壓比約540倍。諧振實(shí)現(xiàn)了功率MOSFET的軟開關(guān)。
[Abstract]:This paper presents a control mode, which constructs a bipolar high voltage double fast edge pulse source based on Boost converter. Because the diode conversion speed is faster than the active power switch, the output pulse front edge is steeper than the trailing edge, the leading edge time is about 40 as, and then the time is about 160ns. The top of the output pulse is flat, about 350 ns. The pulse source operates in discontinuous mode, and the measured step-up ratio is about 540 times. The soft switch of power MOSFET is realized by resonance.
