Power Management
Keeping Cool
Preventing electronic circuits from getting too hot is not just about cooling but also trying to minimize the excess heat being generated in the first place. For a digital circuit that can be a case of reducing the voltage or clock speed, or dynamically altering the clock speed to suit what is required at the […]
Top power electronics threads on EDAboard.com – October
Industrial grade robust inverter build – I have done a lot of research online about IGBTs, gate drivers, blown up many IR2110s, studied PCB layout considerations, OC/SC protection, current sensors and so on but none of my designs has ever lasted for long when loaded by an actual motor. The waveforms were perfect, but smoke was […]
