Abstract

This paper focuses on low cost and low component count, multiple-output power conversion. The work is particularly applicable to both isolated and non-isolated conversion to multiple independently regulated low voltage outputs. The topology employed is a switch-mode current source feeding interleaved switched capacitor outputs. Several advances are presented. The output switches for the topology are implemented with two types of silicon for uni-directional current flow. Firstly, with newly available power trench JFETs and then with proposed new "body-diode-less" N-Channel MOSFETs. These have their internal body (base) regions separated from their source regions. A novel control scheme involving closed-loop control of the switching frequency to maintain the optimal source current is presented.
