Biasing bipolar transistor circuits
Bipolar transistors used in linear applications need “biasing”, as do other transistors (JFET, MOSFET) when used for linear applications rather than as switches. When used as a “switch” you simply want the transistor to be ON or OFF and don’t really care about having in-between states, although when you are switching high power or switching […]
85-V MOSFETs have adaptive dead-time, shoot-through protection
Micrel Inc., (Nasdaq:MCRL) introduced the MIC4606, an 85V Full-Bridge MOSFET driver that features Adaptive Dead Time and Shoot-Through Protection. The device is part of Micrel’s highly successful 85V MOSFET Driver family first launched in 2013 and is designed to focus on the growing power needs of multiple applications. The 85V MIC4606 family is part of […]
Gallery: Scenes from the IEEE ECCE conference
The IEEE Energy Conversion Congress and Exposition took place last week in Pittsburgh. The clear trends based on exhibits on the show floor included a lot of interest in SiC power devices and in alternative topologies for inverters. Here are a few of the more interesting sites we encountered there. SiC on display The Center […]
SiC MOSFETs will power solar inverters
