When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable prices.

This article series is in the Power Management topic within our Series Library and the Power Supply Design topic within our TechXchange Library Members can download this three-part mini tutorial ...

The supply transformer and backup UPS must be rated at 200 A × 400 V = 80 kVA. But if the power factor of the loads is only 0.6, then only 80 kVA × 0.6 = 48 kVA of real power are being consumed.

One of the most important concepts for anyone using power supplies is understanding constant voltage (CV) and constant current (CC). For engineers getting started with power supplies they must know ...

Fig. 1 shows a transformer in a Wye configuration. (Fig. 1) Three-phase Wye connection Delta A three-phase Delta is a 240 VAC feed with one phase center-tapped as shown in Fig. 2 to provide two 120 ...

The TDDCDC-TPH-IN-BI-LLC-300W-RD design uses TP65H150G4PS 150 mOhm SuperGaN® FETs in a robust TO-220 package to power a high performing, high efficiency energy harvesting and distribution battery ...

Microchip Technology and power supply maker Delta Electronics are to collaborate on silicon carbide (SiC) based power supply design. “SiC is increasingly important in power solutions because of its ...

Next-generation NeoPower™ product for multi-output industrial and medical power supplies combines best-in-class power density of 18 W/in 3 with extensive digital communication options DENVER ...

But it’s also rated for more powah: The 28-pin connection is rated for up to 900 watts, presumably delivered by multiple rear-mounted power supply cables. Multiple competing standards are always ...

Remote patient monitors (RPMs) are continuously evolving to include more features that enable doctors to gain greater insights into their patients’ health. These features create greater demands on the ...

The June 30 educational event from Machine Design, in conjunction with Electronic Design, will feature essential DC-DC power-supply design content. Power supplies and power-management systems are ...
