Power Supplies & Magnetics
March 2020
The worst collateral damage of COVID-19 is the decimation of global commerce, and trade shows have been hit especially hard – tough to practice “social distancing” with a few thousand people (or more) clustered together. And one of the most unfortunate victims of this new, quarantined reality was the 2020

Figure 1. One possible FPGA power tree: a high voltage input supply (for example, 12 V, 24 V, or 48 V) is stepped down to an intermediate voltage bus feeding the POL regulators that power the FPGA
Since the 1980s, FPGA resources, speed, and efficiency have improved rapidly, making FPGAs the go-to solution for a wide variety of computing and processing applications, especially when production volume doesn’t justify application-specific integrated circuit (ASIC) development costs. FPGAs have advanced

Figure 1: Delta configuration
Power supplies with a rated output of greater than 2,500W often require, or have an option for, a high voltage three phase AC input. A load of 3,000W, for example, operating from a single phase 230Vac input will consume 13A (3000W / 230V = 13A). The same load operating from a 400Vac three phase input will draw

Minimising power consumption is a high priority and in digital devices, it is directly related to voltage swing and data rates. Consequently, supply voltages have steadily reduced from 5V to sub-1V with sub-sections of devices having separate supply rails: processor cores between 0.56V to 0.88V on next generation

For many designers these magnetic and electromagnetic components are considered very “low tech”. The reality is, however, that much technology and know-how is applied to designing and constructing these passive components: moving their capability inexorably forward.

COVID-19 has claimed another victim – on Friday, PCIM Europe 2020 was officially postponed.
The good news is that PCIM will be delayed (until July 28-30) instead of cancelled. And the decision was almost entirely out of the show organizers’ hands.
