초록
Recently, According to increase of power demand, it was increased a demand that switching power supply have characteristic of low-loss and high-efficiency. So increase of using device, the failure rate increases and service life problem arises. Even though normal circuit protection is applied in designing stage, it is often hard to identify the cause of malfunction in certain cases such as fatigued power supply due to over-running, malfunctions of main elements or over heating. This report will cover experimental results with the prototype we made, that monitors the efficiency of switching power supply and that protects a circuit when it drops below the standard value.
