High power density has steadily ramped up since the latter part of the 1980s. Power converters are ever being made smaller in size and lower in weight. Good reasons for this miniaturization trend stem from demands in applications such as aerospace and satellites, and biomedical devices. And the industry continues to try to meet customer needs for portable power-supply devices like uninterruptible power supplies (UPS), desktop and laptop power supplies, portable battery chargers, power for telecom, information technology, and data servers.
What are some of the high-power-density power-supply design architectures that stand out in the industry? Let’s take a look.
