Step by Step: Make an Inverter’s power stage (MOSFET)
Here I show how to make the Power stage of an homemade inverter. I’m using the following, Old UPS transformer 2x Alluminium Heatsink 2x N-MOSFET (IRF540N, P55NF06, B150NF55 etc) Screws, […]
Convert square wave Inverters to sine wave Inverter
There’s pretty easy to make square wave inverter circuit in the internet. But to run most load like fan, TV, etc you need to have a sine wave inverter. Making […]
Inverter Oscillator Board using Flip Flops 74LS112
I’ve found this board in many inverters, and it works great with transistor type inverters. I have tested this kit with Mosfets, but the gate triggering was low, and […]
CFL emergency kit PUSH PULL application 12Volt 18Watt
Push-pull applications makes a more reliable waveform output than that of a flyback converter. Thus it can be used. The below circuit have a push-pull transformer, with two Switching transistors, […]
