I have been put forth with this question many times in this blog, how do we add a changeover selector switch for automatically toggling of an inverter when AC mains […]

A very simple low battery cut-off and overload protection circuit has been explained here. The figure shows a very simple circuit set up which performs the function of an overload […]

A relatively simple 1000 watt pure sine wave inverter circuit is explained here using a signal amplifier and a power transformer. As can be seen in the first diagram below, […]

In this post we discuss how to build a simple UPS circuit for backing up computers or PCs during sudden power failures or brownouts. Introduction Normally when we talk about […]

The common problem with many low cost inverters is their incapability of adjusting the output voltage with respect to the load conditions. With such inverters the output voltage tends to […]

Making a power inverter circuit rated above 2000 VA is always difficult, mainly because of the involved transformer dimension which becomes quite huge, unmanageable and difficult to configure correctly. Introduction Power inverters […]
