1. A step-up converter, comprising:

  • a boost converter having a first inductor;

    a second inductor paired on a core with the first inductor; and

    a half bridge rectifier circuit coupled with the second inductor to generate a direct current output across an output capacitor;

    wherein the half bridge rectifier circuit comprises;

    a first diode and a first capacitor connected to the second inductor to form a first loop to allow electric current to go through the inductor in a first direction; and

    a second diode and a second capacitor connected to the second inductor to form a second loop to allow electric current to go through the inductor in a second direction, wherein the first and second capacitors are series connected with the output capacitor and the direct current output is taken across the series connected first, second and output capacitors.
