With the expansion of urban population and construction scale, the increase of various electrical equipment, the increasing electricity consumption, and the frequent overload operation of urban power supply equipment, the electricity environment has become increasingly harsh, and the "test" of power supply has become increasingly serious. According to statistics, electrical devices are subjected to various power supply issues around 120 times a day, and 60% of electronic device failures come from the power supply. Therefore, the importance of power supply issues is increasingly prominent. As a supporting role, the power supply with less capital investment has been paid more and more attention by manufacturers and researchers, and the power technology has developed into a new technology. Small power devices have integrated more and more new technologies. For example, switching power supply, hard switching, soft switching, parameter stabilization, linear feedback stabilization, magnetic amplifier technology, CNC voltage regulation, PWM, SPWM, electromagnetic compatibility, and so on. The actual demand directly drives the continuous development and progress of power supply technology. In order to automatically detect and display current, and to have automatic protection function and more advanced intelligent control in case of overcurrent, overvoltage, and other hazardous situations, power supply technology with sensing detection, sensing sampling, and sensing protection is gradually becoming a trend. Sensors for detecting current or voltage have emerged and become popular among power supply designers in China
