Abstract

A primary side regulated isolation voltage converter. The primary side regulated isolation voltage converter comprises a control module and a ripple control circuit. The control module receives the voltage feedback signal and determines whether the isolation voltage converter operates in a light load state. When the isolation voltage converter operates in a light load state, the ripple control circuit senses the ripple of an output voltage signal to generate a ripple signal, and compare the ripple signal with a ripple threshold. When the ripple signal is larger than the ripple threshold, the isolation voltage converter jumps out the light load state.
