Abstract
Small duty cycle, short on-time, and high switching loss are the ultimate limit for high performance nonisolated DC/DC converter designs and applications. This paper introduces a HV input high frequency nonisolated DC/DC converter that can effectively correct all of the above mentioned problems. Significantly reduced MOSFET switching and conduction losses enable high frequency operation without thermal penalty of the power semiconductor devices. Since duty cycle can be extended and programmed in this topology, true ripple cancellation in multiphase configurations is achievable.
