Here I have explained about a couple of simple circuit configurations which will convert any low power inverter to a massive high power inverter circuit. You’ll find a plenty of small and medium sized inverters in the market ranging from 100 to 500 watts, the same may be seen posted in this blog. Upgrading or […]
High
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 […]

Connecting Voltage Regulators 78XX in Parallel for High Current
In this post we investigate how to connect popular voltage regulator ICs such as 7812, 7805 in parallel for acquiring high current output from the ICs. Voltage regulator chips mostly have their maximum current output specs fixed to some predetermined levels. Increasing them to a higher level would normally call for external out board transistors […]
