Output control of a super lift re-lift Luo dc-dc converter

Abstract

This report describes the design and implementation on control of a single-phase inverter and a super lift re-lift Luo converter. It will focus more on the super lift re-lift Luo converter which is implemented by applying voltage lift technique to the circuit. A super lift re-lift Luo converter is a DC-DC boost converter which allow the output voltage to increase gradually in a geometric progression instead of in an arithmetic faction. Besides, a voltage-mode controller is built to regulate the output voltage of the converter. The simulation result on the single-phase inverter is presented to illustrate the open-loop feature. The experimental results are also presented to illustrate the effects of the voltage-mode controller on the converter in the present of transient response, load interference, source voltage and reference voltage change.
