GaN Power Switch for Power Distribution Protection

GaN Power Switch for Power Distribution Protection 150 150
Author(s): Ronald Hassib Galvis Chacón, José Alexandre Diniz, Saulo Finco

Abstract:

The electrical power system (EPS) of satellites requires protection devices to isolate failures in short-circuit conditions that can occur in payloads due to various sources, such as debris, mishandling, or radiation. Latching current limiter (LCL) implemented with a pMOS power transistor is typically used for this task. Radiation can also …

A Single-Stage Dual-Output Regulating Voltage Doubler for Wireless Power Transfer

A Single-Stage Dual-Output Regulating Voltage Doubler for Wireless Power Transfer 150 150
Author(s): Tianqi Lu, Kofi A. A. Makinwa, Sijun Du

Abstract:

A single-stage dual-output regulating voltage doubler (DOVD) is proposed for biomedical wireless power transfer (WPT) systems. Derived from the full-wave voltage doubler (VD) topology, it achieves ac-to-dc rectification and dual-output voltage regulation in a single stage by using only two power transistors. The DOVD’s inherent voltage conversion ratio (VCR) …
