Understanding Buck Power Stages Mode Power Supplies
www.ti.comUnderstanding Buck Power Stages in Switchmode Power Supplies 3 2 Buck Power Stage Steady-State Analysis A power stage can operate in continuous or discontinuous inductor current mode. Continuous inductor current mode is characterized by current flowing continuously in the inductor during the entire switching cycle in steady state operation.

What You Need to Know About SCR Power Controllers
www.advancedenergy.comcompared to switch-mode power supplies. The low loss designs can operate in ambient temperatures up to 55°C (131°F) (using de-rated SCRs), reducing the need for air conditioning and other associated costs. Furthermore, many utilities charge a penalty if a certain power factor, typically 0.9, is not met. SCR power
