This paper investigates a new reconfigurable switched-capacitor (SC) based partial power architecture which enhances the performance of radio frequency (RF) resonant DC/DC converters with gallium nitride (GaN) power devices. The proposed architecture has a comprehensive compatibility with existing RF and SC topologies and improves the performance of RF converters through partitioning of energy conversion...
Power decoupling is required to balance the difference between constant power at PV side and double frequency pulsating power at load side in single phase AC system. The balance power is generally handled by circuit passives. This paper proposes decoupled power control for grid connected PV systems using an embedded decoupling capacitor in a doubly grounded boost buck (Ćuk) derived micro inverter...
This paper proposes a new single-input three-output DC-DC buck converter. The proposed topology has two less switching devices than that of a conventional converter. This reduction in switching devices results in lower cost and a more even distribution of power losses among the switching devices. A comprehensive small signal Modeling and control strategies for the proposed converter will be presented...
The paper presents a new bridgeless Power Factor Correction (PFC) topology, using a recently proposed controllable LCL filter, namely Active Virtual Ground (AVG) to achieve efficient power conversion and high frequency (HF) common mode voltage (CM) reduction. The proposed PFC circuit consists of high frequency semiconductors for shaping inductor current, and low frequency semiconductors to form two...
