The efficiency of a power supply has a direct influence on reliability. It is essential – especially in the case of convection-cooled devices – on the one hand for a small and on the other hand a reliable power supply. Without additional ventilation, heat can only be dissipated to a limited degree and the designer of a power supply must be very careful to achieve the lowest possible generation of heat. Even the other essential system elements benefit from low power losses and therefore also minimal heat generation. An increasing number of power supply manufacturers thus strive for high efficiency. This article should help users determine the accurate efficiency and thus the power losses of a power supply so that they don’t have to rely completely on data sheets with often optimistic and scarce information.
