Abstract

In this paper, feedback control design of Zero-Voltage-Switched Quasi-Resonant dc-dc converters is presented. The power stage model is derived by a method of circuit averaging, while the control stage model, consisting of an Error Amplifier (EA) and Voltage Control Oscillator (VCO), determined by the input/output relationship of the circuits. The obtained models are used in feedback control design of the prototyped converter. Test results show that the converter exhibits good output voltage regulation and fast transient response to a step-load change. © 2008 IEEE.
