Abstract

This paper describes the derivation of a practical solution to designing a medium-power non-isolated DC/DC power converter with very low output ripple voltage and very high output voltage slew-rate capability. The converter is intended for powering and efficiency-optimizing an RFPA (Radio Frequency Power Amplifier) in a communications system base station. A simple and effective analog control scheme for the converter (buck with 4^th order output filter) is developed, along with an accurate linear model The proposed approach is verified experimentally by a 500W output prototype, capable of greater than 1V/μs slew rate with 40mVpp of output ripple and efficiency above 90%.
