High performance forward converter in non-isolated configurations

Small duty cycle, short on-time, and high switching loss are the ultimate limit for high performance non-isolated DC/DC converter designs and applications. This paper introduces a forward converter in non-isolated configuration that can effectively alleviate 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 multi-phase configurations is achievable.
