Abstract
A power converter having a two stage boost circuit and a small boost converter. The main power flow for the power converter is via the two stage booster circuit having a single switch. The voltage spike of the switch is clamped by a diode and a capacitor. The energy at the capacitor is transferred to the power converter's output terminals by the small boost converter. The two stage boost converter topology enables the use of much lower voltage and Rdson MOSFET switches so as to reduce cost, switch conduction loss and turn on loss.
