Bootstrap circuit for gate driver optocoupler

July 22, 2014 4:27 pm | by See Leng Kian, Principal Product Engineer of the Optoelectronic Business Unit of Fairchild. | Comments

IGBTs are commonly used in inverter systems, which are used for adjustable motor drives, solar inverters and UPS. Inverters can be single-phase or three-phase, which is basically an extension of the H-bridge. Figure 1 illustrated one of the six gate driver optocouplers from Fairchild Semiconductor driving the IGBT module for the implementation of the three-phase inverter system.

Any way the wind blows....

July 21, 2014 9:14 am | by Joshua Israelsohn, Director, JAS Technical Media | Comments

When I hear or read the phrase wind power, I immediately imagine tall-towered machines with tri-blade impellers tracing out huge arcing sweeps against partly cloudy skies. Your imagery may vary. Globally, wind generation capacity climbed to 318 GW in 2013 and has increased, year-over-year, an average of 37 MW since 2008....
