摘要

Power supplies for Information and Communication Technology (ICT) are facing extremely difficult challenges to sustain increasing energy demands in systems that must guarantee high power-density and high efficiency. All of these characteristics must be ensured over the entire load variation and across universal mains input voltage ranges. Meeting these requirements will require significant technology advancements in system architectures, semiconductor devices and packaging/thermal design. Compact and efficient systems require a design approach which is different from that of traditional analog ICs. While the standard approach is based on the use of a boost type PFC and a regulation stage, both of which are controlled using analog PWM regulators, the new, fully digital approach relies on the use of microcontrollers to control both the PFC and the DC-DC stage. After a general description of the topology adopted, this article focuses more on the behavior of MDmesh(TM) DM6 MOSFETs vs MDmesh(TM) DM2 MOSFETs, used in a 2 kW ACDC switch mode power supply with full digital control based on the STM32F334C8 microcontroller, and on the performances of MDmesh(TM) DMx devices vs the main competitors that provide MOSFETs with fast diode technology.
