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, the configuration is a simple mosfet based designed for amplifying current at +/-60 volts such that the connected transformer corresponds to generate the required 1kva […]

Simple SG3525 Sine Wave Inverter Circuit Explained
In this post we will discuss two methods of designing pure sine wave inverter circuits using 555 IC based SPWM processing. In the first concept we connect the 555 processors directly with the SG3525 outputs and do the sine wave conversion directly at the MOSFET gates. In the second concept we do it externally and […]
Pseudo-sinusoidal IC 4047 Inverter Circuit
From a continuous source, battery, or vehicle alternator, it is possible to produce a 50 Hz voltage/pseudo-sinusoidal waveform, using this simple IC 4047 inverter circuit. The design is capable of operating many low-power devices that require a voltage of 220 V AC, typically supplied by the AC mains grid distribution network. The power of this […]
Design your own Sine Wave Inverter Circuit from the Scratch [Tutorial]
In this article I have explained comprehensively regarding how to design a sine wave inverter without any form of coding or complex circuit designs. The included designs are simple yet extremely precise with their sine waveform structure. You might have often felt discouraged, thinking that making a sine wave inverter from the scratch can be […]
IC IR2111 H-Bridge Inverter Circuit with Shut Down
This circuit is basically a H bridge inverter where two IC IR2111 are working for driving four MOSFETs that are connected in H bridge way. We also see that there is a overload and over current shut down using BC547 small transistors. So what happens is that we can run a load with AC waveform […]
IR2111 H-Bridge Inverter Circuit with Soft Start
Here we see this circuit diagram which is full H-Bridge using 4 power MOSFETs and 2 IR2111 high side driver ICs. That means this circuit is for making full bridge inverter which converts DC into AC. Power Supply Part We have +600V DC at top rail, written as +600V max. And ground (0V) at bottom. […]
