Abstract

This paper aims to provide a practical insight into the use of a novel resonant gate drive system to efficiently drive both the power switches in a switched mode power supply, without the requirement for level shifting or bootstrapping circuitry. At present there are two popular methods to drive high side N-channel devices in low voltage applications. The circuit presented here overcomes the limitations of these solutions without a part number proliferation. The theoretical characteristics of the topology are examined in a detailed mathematical analysis suite. Simulation and experimental results emphasize the advantages of the proposed topology
