Convert a Square Wave Inverter into a Sine Wave Inverter
In this post I have explained a few circuit concepts which can be employed for converting or modifying any ordinary square wave inverter to sophisticated sine wave inverter design. Before studying the various designs I have explained in this article, it would be interesting to know the factors which typically makes a sine wave inverter […]
300 Watts PWM Controlled Pure Sine Wave Inverter Circuit
The following article which discusses a 300 watt pure sine wave inverter circuit with automatic output voltage correction, is a modified version of one of my previous posts, and was submitted to me by Mr. Marcelin. I have explained more about the converter implementations. The Design The idea was inspired by the design presented in this article […]
IC 556 Pure Sine Wave Inverter Circuit
In the following post I have explained a pure sine wave inverter circuit using the IC 556 which forms the main sine wave processor device in the circuit. How it Works The presented design actually produces a modified sine wave output, but the waveform is highly processed and constitutes an exact equivalent of a sinusoidal […]
Make This 1KVA (1000 watts) Pure Sine Wave Inverter Circuit
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 […]
