Efficient power electronic design hinges on the availability of accurate and predictive SPICE models. This paper proposes novel physical and scalable SPICE models for power electronic semiconductors including wide−bandgap devices.
FREQUENTLY ASKED QUESTIONS ON CURRENT SENSE AMPLIFIERS
What exactly is a current sense amplifier? Why is low input offset voltage (Vos) important. Check out answers to these and other common questions on current sense amplifiers.
KEY STEPS TO DESIGN AN INTERLEAVED PFC STAGE
This approach offers several merits like the ease of implementation, the use of more but smaller components, a drastic reduction of the input and bulk rms currents or a better heat distribution.
POWER INTEGRATED MODULES FOR SOLAR INVERTERS
We will introduce Q0, Q1 and Q2 series of power modules for solar inverters rated up to over 100kVA along with NCD family of non-isolated high current IGBT drivers to achieve lower switching losses.
HOW TO ACHIEVE LOW THDI AND HIGH EFFICIENCY OVER A WIDE OPERATING RANGE FOR CRM BOOST CONTROLLERS
Check out how we do this by transitioning between CrM and DCM modes to reduce switching frequency as the load is reduced.
HOW TO PROTECT CIRCUITS FROM OVERCURRENT DANGERS
Over-current or over-voltage conditions can pose a danger to your electronic systems, and possibly the people around it. Monitoring the current or voltage is critical in power supply, motor control and energy monitoring systems. In this video, we have designed a current monitoring circuit using the NCS214R current sense amplifier and NCS2250 comparator, to monitor a 100mA current threshold and demonstrate the circuit performance when the load is changed to trigger an over current condition.
