1 工艺状况双极型硅二极管通常被用于变换器中。在硬开关电路中,它们的反向恢复会在二极管本身以及对应的晶体管中产生损耗。同样,对于软开关电路,反向恢复也是一个限制性因素。人们尝试去优化双极型硅二极管的电气特性,但很难在器件本身物理结构上实现突破。硅肖特基二极管是一种更新了的器件,由于具有低电阻率,它的反向恢复速度比较快。但是这种二极管的阻断电压只有100V左右。除此之外还有一些采用新型材料如金刚砂,加工
1 process conditions Bipolar silicon diodes are usually used in the converter. In hard-switched circuits, their reverse recovery causes losses in the diodes themselves and in the corresponding transistors. Similarly, reverse recovery is also a limiting factor for soft-switching circuits. People try to optimize the electrical characteristics of bipolar silicon diodes, but it is difficult to achieve a breakthrough in the physical structure of the device itself. Silicon Schottky diodes are newer devices that have faster reverse recovery due to their low resistivity. However, this diode blocking voltage is only about 100V. In addition there are some using new materials such as emery, processing
