Analytical modelling of three-phase four-wire grid-connected inverter under unbalanced conditions applying digital controllers

Systems Science & Control Engineering
This paper presents an analytical model for a two-level three-phase four-wire grid-connected voltage source converter (TGC-VSC) controlled by digital pulse-width modulation (DPWM).

Time-Domain ADPLL BPSK, QPSK, and 8PSK Demodulators

Journal of Electrical and Computer Engineering
Time-domain all-digital-phase-locked-loop phase-shift-keying (PSK) demodulators are proposed for BPSK, QPSK, and 8PSK signals. The demodulator architectures are highly suitable for low-voltage nanoscale CMOS techology.
