A Technique for Reducing Diode Reverse-Recovery-Related Losses in Boost converters

다이오드 역방향 회복에 의한 손실을 감소시킨 부스트 컨버터

This paper proposes a circuit technique that reduces losses cauased by reverse-recovery characteristics of the diode in converters. In high voltage, high power, Reverse recovery characteristics of the diode gives large stresses to switching devices. To solve the problem, we propose a circuit with active snubber between diode and switch. By controling di/dt rate of thr diode, the proposed technique reduces the losses and the stresses of switching devices.
