One big issue that most GTI manufacturers struggle to implement effectively is, what is commonly known as “islanding”, the following discussion throws light on this important factor and tries to find a solution. The issue was pointed out and clarified by Mr. Dennis, I have explained more. What’s GTI Islanding G’day, With any luck at […]

Troubleshooting Inverter Output Voltage Drop Issue
The post presents a discussion regarding the troubleshooting of a 4047 IC based inverter output voltage drop problem on connecting a load. The solution was requested by Mr. Isaac Johnson. The Issue Good day sir, I am a reader of your blog and an electronics hobbyist. I constructed a square wave inverter with a filter […]
5kva Ferrite Core Inverter Circuit – Full Working Diagram with Calculation Details
In this post I have explained the construction of a 5000 watt inverter circuit which incorporates a ferrite core transformer and therefore is hugely compact than the conventional iron core counterparts. Block Diagram Please note you can convert this ferrite core inverter to any desired wattage, right from 100 watt to 5 kva or as […]
Dual A/C Relay Changeover Circuit
In this post I have explained a simple relay changeover circuit which may be used for switching a couple of A/Cs or any similar load alternately in order to avoid misuse and save power. Technical Specifications Here is the situation: State: California. Facility: Church. The electric rate is greatly influenced by peak usage in any […]
How to Convert an Inverter to an UPS
An inverter is an equipment which will convert a battery voltage or any DC (normally a high current) into a higher mains equivalent voltage (120V, or 220V), however unlike an UPS inverters may lack one feature, that is these may not be able to switch from mains battery charging mode to inverter mode and vice […]
Simple High voltage Generator Circuit – Arc Generator
A simple high voltage generator circuit is explained here which can be used to step up any DC level to about 20 times or depending upon the transformer secondary rating. Circuit Operation As can be visualized in the shown high voltage arc generator circuit diagram, it employs a standard transistor blocking oscillator configuration for generating […]
