Reflected voltage

WebFor flyback converters with primary reflected voltage for the hold-up, the reflected primary voltage is boosted and regulated with additional circuitry and a storage capacitors will be connected across this to store the energy. This stored energy is generally connected to the input of the LVPS through switch over logic based on the power ... There are several approaches to understanding reflections, but the relationship of reflections to the conservation laws is particularly enlightening. A simple example is a step voltage, (where is the height of the step and is the unit step function with time ), applied to one end of a lossless line, and consider what happens when the line is terminated in various ways. The step will be propagat…
