Summary: This paper proposes a three-port soft-switched DC-DC converter that integrates solar photovoltaic (SPV) source, battery energy storage system (BESS), and DC load. The converter enhances the conventional phase-shifted full bridge (PSFB) DC-DC converter topology by adding a link inductor to create a three-port converter structure and using a secondary passive clamp circuit to minimize circulating current loss. The load port is isolated from the SPV and BESS port through a high frequency transformer. The converter utilizes closed loop controller for maximum power extraction, charge/discharge control, and load voltage regulation.

Summary: This article proposes a three-phase voltage-source converter (VSC)-based isolated matrix-type ac/dc converter for wind energy conversion system. The conventional line-frequency transformer is replaced by a high-frequency transformer (HFT), eliminating the need for intermediate electrolytic capacitors. The bidirectional switches used in the conventional matrix converter are also eliminated, simplifying the commutation scheme and reducing conduction loss. The proposed converter can be seen as a dual VSC circuit, employing voltage vectors-based space vector modulation and control schemes for nonisolated VSCs. A commutation strategy is proposed for the leakage-inductor current of HFT to ensure safe operation. Simulations and experiments are conducted to verify the performance of the proposed converter.

Summary: This work presents an offline power supply with fully integrated power stage in 0.18 Am high-voltage (HV) CMOS silicon on insulator (SOI). It supports both ac-dc and dc-dc conversion from 15-400 V input down to 3.3-10 V output and is optimized for applications below 300 mW such as the Internet of Things (IoT), smart home, and e-mobility. An active zero-crossing buffer enables on-chip integration of the HV buffer capacitor. Below 150 V, constant ON-time control is based on voltage intervals, sensed by ten HV threshold-detection circuits. Above 150 V, the converter operates in the resonant mode. It achieves a superior power density of 458 mW/cm(3) and 84% peak efficiency.
