Thus the Baker clamp has satisfactorily solved two significant problems. It prevents a sufficient forward bias on the base-to-collector junction to cause appreciable storage time. It also permits the circuit to work equally well with large changes in load current and over a large production spread in transistor beta because of the redistribution of input currents between D2 and D3 as base current demands change.
However, it is still desired to provide reverse base current to Q1 at the instant of turnoff to speed up turnoff time and provide a -1-to -5-V reverse base bias. This is prevented by the blocking action of D2, but by adding the “reach-around” diode D1, across D2, it becomes possible. It now only remains to find a low-parts-count scheme to provide the large forward current Ib1 for turnon, an equally large reverse current Ib2 , and a reverse voltage bias at the base for turnoff. This is easily achieved with the transformer-coupled scheme of the following section.

因此，贝克钳已圆满解决的两个重要问题。它妨碍着偏见有足够的基础上，对集电极结造成可观的储存时间。它也允许电路工作同样大负载电流的变化，并在大生产中推广试用，因为晶体管的再分配输入电流之间的D2和D3的基地目前的需求变化。
但是，它仍然是希望提供扭转目前的基础上，以第一季度即时的倒胃口加快关机时间，并提供1至5电压反向基地偏见。这是阻止拦截行动D2中，但增加了“达到全能”二极管D1和跨越D2中，它成为可能。它现在唯一的是如何找到一个低部分计数计划，以提供大型正向电流Ib1的turnon ，一个同样大的反向电流Ib2和反向电压偏置在基地倒胃口。这是容易实现的变压器耦合方案下一节。
你才给5分啊，上面的仅供参考啊
