Abstract
In order to enable the excellent reliability in boost converter with high voltage conversion ratio, we proposed cascade topology with seesaw stress relief control to reduce stress of power MOS. The proposed robust cascaded boost converter (CBC) only needs 68% duty ratio instead of 90% in conventional one. The proposed seesaw control strategy to make the first-stage maximum current with low voltage, but the second-stage maximum voltage with low current. The proposed see-saw stress relief method lowers the conduction loss and increase the reliability in the application of high voltage conversion ratio. Simulation and experiment results validate the effectiveness of reducing stress and the heat simultaneously.
