Grid Tie Inverter Schematic and Principals of Operation
WHAT IS IT? Grid-interactive or grid tie inverter (GTI) is an electronic device that converts direct current (DC) voltage to alternating current (AC) voltage and that can operate in parallel with the electric utility grid. The DC voltage normally comes from photoelectric panels or energy storage batteries. GTIs allow interconnection of renewable energy systems with the grid. The power processing circuits of a GTI have similar working principle as that of a conventional stand-alone DC-AC SMPS.

Build an Analog ESR Meter With Moving-Coil Meter Precision
I was always envious of my friend’s analog ESR meter that allowed him to check and find bad capacitors while they were still in circuit. The particular meter he had is no longer available, which meant doing some research to understand how they worked and to come up with my own version.

Calculating mains frequency power transformers
In this page a simple method of calculating mains frequency closed-core power transformers. This is intended for home brewing, repairing and modifying transformers. Please remark that even if this method and some equations could be generalized, only classical cores composed by steel plates are taken into account.
How to Calculate Ferrite Core Transformers
Calculating ferrite transformer is a process in which engineers evaluate the various winding specifications, and core dimension of the transformer, using ferrite as the core material. This helps them to create a perfectly optimized transformer for a given application.

SPWM overmodulation (Υπερ-διαμόρφωση SPWM)
Ενα πολύ χρήσιμο (αν και περισσότερο θεωρητικό...) άρθρο, για αυτούς που ασχολούνται με τα Ηλεκτρονικά Ισχύος (Power Electronics).
Αρκετά εξειδικευμένο για κάποιους βέβαια...
