In the case of Boost PFC circuit, the output voltage is greater than the input peak voltage.

在Boost PFC电路中，输出电压要高于输入电压峰值，而高压输出对IGBT的开通损耗和二极管的反向恢复损耗而言，在PWM硬开关工作状态下都会相当大，因此，一个最大的问题就是如何减小或者消除这两个损耗。

The high efficiency and high power semiconductor laser with multi-active regions which are cascaded by reverse biased tunnel junction has a higher inner quantum efficiency which can larger than 1, so that it can output higher optical power at the same injected current compared with the normal lasers, meanwhile, it can be designed to large coupled optical cavity, so it will increase the limit of the electro-thermal destroy and the COD.

通过反向偏置隧道结将多个有源区级联起来的多有源区耦合大光腔高效大功率半导体激光器从理论上解决了传统激光器存在的问题，由于其内量子效率大于1，可以在相同电流下输出高的光功率，且可以制成耦合大光腔结构，增大了光腔面积，因此相对于传统激光器而言，其电热烧毁和COD水平都会提高。

Remember, too, that once you go ahead with a consolidation deal there is no reverse gear, and so it's vital that you do your research and make sure consolidation is the best way forward for you.

记住，一旦你进行了加固处理并无反向齿轮所以重要的是你和你的研究整理清楚你是最好的路。
