The article focuses on the design of modern mains power supplies. Most designs are extremely compact which result to the dissipation of a substantial amount of power in the form of heat while operating. This often causes the overheating of the power supply's internal components, which lead to an adverse effect on reliability and product lifetime. The problem is often addressed through the use of mechanical fans, which is deemed to have low reliability and cause irritating noise.
