A new cost-effective analog maximum power point tracker for PV systems
TL;DR: In this article, a cost-effective analog MPPT controller is proposed by creating a truth table from the perturbation and observation (P&O) algorithm, the algorithm can be implemented with only several logic gates.
Proceedings ArticleDOI
Hierarchical power management for DC microgrid in islanding mode and Solid State transformer enabled mode
Xunwei Yu,Xu She,Alex Q. Huang +2 more
TL;DR: A hierarchical power management scheme is proposed in this paper for a typical DC Microgrid, including the individual control for distributed renewable energy source (DRER) and distributed energy storage device (DESD).
Proceedings ArticleDOI
Reliability of 4H-SiC SBD/JBS diodes under repetitive surge current stress
TL;DR: In this article, the reliability of power diode under surge current stress is crucial to the applications like motor drives. And the single and repetitive surge reliability of the 4H-SiC Schottky Barrier Diodes (SBDs) and JBS diodes have been tested and the corresponding failure mechanisms studied.

15kV/40A FREEDM super-cascode: A cost effective SiC high voltage and high frequency power switch
TL;DR: In this article, a 15kV/40A three terminal power switch, the FREEDM Super-Cascode, is reported for the first time which is based on series connection of 1.2kV SiC power devices.
Proceedings ArticleDOI
A novel light load performance enhanced variable-switching-frequency and hybrid single-dual-phase-shift control for single-stage dual-active-bridge based AC/DC converter
TL;DR: A novel variable-switching-frequency and hybrid single-dual-phase-shift (VSF-SDPS) control strategy is proposed and analyzed for the DAB based single-stage topology that eliminates the bulky DC link bus capacitor and operates the front-end with only 60Hz switching frequency.
