Abstract :
This paper presents techniques which can eliminate or reduce the effects of the positive or RHP zero which appears in the small-signal duty-cycle to output transfer function of certain DC-DC power converters. Several techniques are presented along with the theory, simulation results and experimental results supporting each technique
