A power module is a power supply that can be directly mounted onto a printed circuit board. Its characteristic feature is the ability to provide power to dedicated integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field-programmable gate arrays (FPGAs), and other digital or analog loads. The converter input of AC/DC power modules is alternating current (AC) with a frequency of 50/60Hz. As it is necessary to rectify and filter the output to provide direct current (DC) power, these modules are widely used in various fields such as medical equipment and home appliances.
