In this article I have explained a couple of inverter circuits featuring an automatic feedback control for ensuring that the output does not exceed the normal specified AC output level, and also does not exceed the specified overload conditions. What is Feedback Control in Inverters A feedback control in inverter is generally incorporated to control […]

Class-D Sinewave Inverter Circuit
A sinewave inverter using class-D amplifier functions by converting a small sinewave input frequency into equivalent sine PWMs, which is finally processed by an H-bridge BJT driver for generating the mains sinewave AC output from a DC battery source. What is Class-D Amplifier The working principle of a class-D amplifier is actually simple yet extremely […]
Arduino Full-Bridge (H-Bridge) Inverter Circuit
A simple yet useful Microprocessor based Arduino full-bridge inverter circuit can be built by programming an Arduino board with SPWM and by integrating a few mosfets with in H-bridge topology, I have explained the details below: In one of our earlier articles I will comprehensively explained how to build a simple Arduino sine wave inverter, […]
