Radio frequency converters（RFC）

High-power radio frequency converters (RFCs) need to deliver a wide-range power against variable load impedance. However, it is difficult to achieve a wide-range power regulation and zero voltage switching (ZVS) simultaneously. To address thi.s issue, this paper proposes a DC-link parallel AC-link series (DPAS) multiple power amplifier (MPA) architecture with outphasing modulation. The generalized mathematical model of the proposed topology is presented. The system’s soft-switching range and criterion are analyzed.
