TORPEDO: an all-purpose switched-mode power supply

Having explained the theory, let’s see in practice the project of the SEPIC power supply.   In this post we discussed – on a theoretical level (even if in a simplified way) – the SEPIC switching converters, also highlighting advantages and disadvantages, and giving you the basics for the calculation of their components. Let’s get to the heart of the project, now; we will present a practical application ...

A Cost-efficient Super-Cascode SiC Switch

Researchers have created a high voltage and high frequency silicon carbide (SiC) power switch that could cost much less than similarly rated SiC power switches. The findings could lead to early applications in the power industry, especially in power converters like medium voltage drives, solid state transformers and high voltage transmissions and circuit breakers. Researchers at North Carolina State Univers ...

Power Management of Xilinx ZedBoard using MMPF0100

Summary This reference design is a power management of Xilinx ZedBoard using MMPF0100 Power Management Integrated Circuit (PMIC). A PMIC is an IC for managing power requirements of the host system and is commonly used in a system-on-chip (SoC) device. On the other hand, the Xilinx ZedBoard, a development board based on Zync-7000 AP SoC, provides appropriate hardware capabilities for interfacing with a numbe ...
