Stepping Inductor For Fast Transient Response Of Switching Converter

总结

A Fast Transient Response Converter Is Disclosed Which Makes Use Of Stepping Inductor In A Switching Converter To Speed Up Output Voltage Response Under Fast Transient Condition. The Inductive Element In A Switching Converter Is Replaced By Two Series Or Parallel Inductive Elements, One Of Which Has A Smaller Value Of Inductance Than The Other. During The Fast Transient Period, The Inductor With Larger Inductance Value Will Be Shorted To A Voltage Source. The Total Inductance Will Be Greatly Reduced And Thus Allows Rapid Current Change During The Transient Change.
