00925njm 22002777a 4500 dc Yousefzadeh, Vahid author Alarcón Cot, Eduardo José author Maksimovic, Eduard Alarcón And Dragan author 2006-03 This letter proposes a three-level buck converter for tracking applications such as envelope-tracking in radio frequency power amplifiers (RFPAs). It is shown that the three-level buck converter can offer advantages in terms of switching ripples, losses, bandwidth, or the size of magnetic components compared to a standard buck or a two-phase buck converter. Experimental results illustrate improved efficiency and ripple rejection in an RFPA envelope-tracking application representative for low-power battery-operated systems.
