Power modules are widely used in switching equipment, access equipment, mobile communications, microwave communications and optical transmission, routers and other communications fields and automotive electronics, aerospace and so on. In the North American market, power modules need to obtain UL certification in order to obtain higher market recognition.
A power supply module is a power supply that can be mounted directly on a printed circuit board and is characterized by providing power for application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field programmable gate arrays (FPGAs), and other digital or analog loads.
Power module as the survival of modern science and technology power source, has become one of the most critical components, the reliability of the power supply will affect the reliability of the equipment to a large extent, so the reliability of the power supply test has become the premise of all parameters, performance guarantee.
