Flyback transformers (actually coupled induc-tors) are covered in a later Section. For more spe-cialized applications, the principles discussed herein will generally apply. Functions of a Transformer The purpose of a power transformer in Switch-Mode Power Supplies is to transfer power efficiently

WebDiscontinuous Flyback Supply’s Building Blocks The off-line flyback power supply can be broken down into building blocks to make it easier to understand and design. The following is a block-by-block description of the Micrel MIC38C43 reference design. MIC38C43 Controller Block (Figure 1) The MIC38C43 uses current-mode control to adjust the PWM Web提供用Mathcad解决物理问题1文档免费下载，摘要:一：范德瓦耳斯方程原理：1分子固有体积修正在理想气体状态方程中，容器的体积V就是每个分子可以自由活动的空间，如果把分子当作有一定大小的刚性球，则每个分子的有效活动空间将不再是V。设1mol气体占有体积Vm，其中分子能自由活动的空间为Vm-b campsites burton bradstock dorset

WebA variable frequency version of flyback converter, commonly known as Quasi-resonant (QR) ZVS fly- back, is largely used in certain applications, such as SMPS for TV, though it is well suited for other ap- plications too. This peculiar topology features several merits.
