As power electronic switching techniques advance, there is an increased need to accurately measure current for feedback control and system monitoring. There are several methods to achieve this, with each method having advantages and limitations. This article focuses on current measurement methods that require relatively high accuracy and bandwidth, such as those used to measure current on the inpu...

Servers and racks used in datacenters have undergone a considerable increase in power, going from a few hundred watts to multiple kilowatts. The distribution of these higher power levels on multiple servers inevitably generates greater power losses and hinders efficiency. This aspect can be mitigated by transiting from a traditional 12V distribution voltage to 48V. The increase in distribution vo...

In typical hot-swap or electronic fuse (e-fuse) applications, great care must be taken when selecting the MOSFET to ensure that the safe operating area (SOA) of the device is not exceeded during a soft-start (SS) turn-on. Even if multiple MOSFETs are paralleled, the soft-start condition causes large amounts of thermal stress. Generally, when using discrete MOSFETs in hot-swap and e-fuse applicati...
