Investigation on designing procedure of power supply

Circuit theories describe the behaviors of a circuit, however it is not the full part of knowledge used in the completion of a circuit design. Nevertheless, the rest of part is not commonly discussed or trained. Domain knowledge is mathematically needed to set up a system of homogenous equations and make the system becomes solvable. However, different application and product has different domain knowledge and resulting engineering has no choice but postpone learning that knowledge to the start of their career life, and the worse is that knowledge change from company to company even they product the same kind of product. This Knowledge Oriented design approach required intensive knowledge and skill on engineer, and it also becomes an index of differentiate good and bad engineer. Result Oriented design approach require no domain knowledge, and one can shows the common “try and error” process, is a special kind of Result Oriented approach. Nevertheless, a fast simulator with no extra modeling knowledge can help both Knowledge and Result Oriented design procedure speed up in a much faster way.
