The phase-locked loop (PLL) is applied in grid-tied systems to synchronise converter operation with grid voltage, affecting stability and performance. Synchronous reference frame PLL (SRF-PLL) a popular synchronisation method due its simplicity reliability. Normal SRF-PLL cannot suppress DC offset, causing basic frequency phase oscillations.When irregular, bandwidth should be reduced ensure acc...

BACKGROUND The Institute of Medicine and The Joint Commission have recommended asking sexual orientation and gender identity (SOGI) questions in clinical settings and including such data in Electronic Health Records (EHRs). This is increasingly viewed as a critical step toward systematically documenting and addressing health disparities affecting lesbian, gay, bisexual, and transgender (LGBT) p...

The previously developed GI methods have an arbitrary aspect since they are based on a particular representation of the symmetric group. Here we remove this arbitrariness by optimizing the representation, that is, optimizing the spin-coupling scheme simultaneously with the optimization of the orbitals. The resulting wavefunctions, called the spin-coupling optimized GI or SOGI wavefunctions, hav...

A high frequency dual-buck full-bridge inverter for small power renewable energy applications is proposed in this paper. The implementation of the wide band gap SiC (Silicon Carbide) power device contributes to the high switching frequency of 400 kHz. This high frequency contributes to reduced converter volume as well as improved power density, which greatly strengthens its portability and appl...
