Abstract

The authors describe a regulated, nonisolated Weinberg boost converter with the following advantages: breadboard efficiency from 95 to 97% at 500 W to 1 kW output power; continuous output current with small current ripple; a boost regulator without right-half plane zero effect giving a high bandwidth response; low switching losses (typically 1% at a switching frequency of 350 kHz); conductance control producing typical first order response: and a wide bandwidth voltage regulation loop (10 kHz, with 80° phase margin), giving superior transient response and reduced output filtering
