Here is a simple low power inverter that converts 12V DC into 230-250V AC (DC to AC Converter). It can be used to power very light loads like window chargers and night lamps or simply give a shock to keep the intruders away. The circuit is built around just two ICs, namely, IC CD4047 and IC ULN2004.
[pdf] Use safety circuits in battery packs to check voltage and heat. This makes batteries safer and stops them from overheating. Charge batteries the right way by not overcharging them. Keep the charge under 4.20V per cell to make them last longer and avoid short circuits.
[pdf] This article proposes a 10kW string inverter based on GaN field-effect transistors (FETs). We will also explore the benefits of GaN and highlight the advantages of building such a system for residential solar applications.
