Abstract:
1. A power converter comprising: a boost converter having an input inductor and a switching transistor coupled to the input inductor at a switching node; a first multiplier stage having a first rectifier coupled between the switching node and a first intermediate node, a first stage capacitor coupled to the first intermediate node, a second rectifier coupled between the first intermediate node and a first boost node, and a first resonant capacitor and a first resonant inductor coupled in series between the switching node and the first boost node; a second multiplier stage having a third rectifier coupled between the first boost node and a second intermediate node, a second stage capacitor coupled to the second intermediate node, a fourth rectifier coupled between the second intermediate node and a second boost node, and a second resonant capacitor and a second resonant inductor coupled in series between the switching node and the second boost node; and a quasi-resonant circuit including a third resonant capacitor and a third resonant inductor coupled in series between the first boost node and the second boost node.
