Abstract
In this paper, the isolated full-bridge boost converter with active clamp is described and a new active-clamping algorithm to improve the efficiency is suggested. In the proposed method, the resonance between the clamp capacitor and the leakage inductor is utilized to reduce switching losses. The loss analysis is performed by simulation and the improved performance is confirmed by experimental results.
