12V-220V H-Bridge Inverter DIY Homemade

Introduction

In this video, I have made a 12V-220V H-Bridge Inverter DIY using Arduino. H-bridge is an electronic circuit that switches the polarity of a voltage and is used to allow DC motors to run forwards or backward. I hope yo will enjoy this video.

H-Bridge Inverter DIY Homemade is a great hands-on project to power up some good old household appliances. With a few basic materials, you can easily construct your own H-Bridge inverter which will allow you to turn any direct current (DC) into an alternating current (AC) device appliance, as well as offer more efficient power conversions when powering your appliances. There are plenty of online tutorials that walk you through assembling and using the inverter but the basics involve connecting four transistors in an H bridge configuration on a breadboard and making sure they line up correctly. Once assembled, you can use it to convert AC to DC and vice versa, so have fun hooking up your doorbells or battery chargers with ease!

Changing the polarity of the energy delivered to the DC motor is used to alternate the course of rotation. Apart from converting the rotation course, the H-bridge can offer extra operation modes, “brake” and “loose run till frictional stop”. The H-bridge association is commonly used to oppose the polarity/course of the motor, however also can be used to ‘brake’ the motor, in which the motor involves an unexpected stop because the motor’s terminals are shorted. In shorted case, the kinetic power of a rotating motor fed on hastily in the shape of electrical contemporary within the shorted circuit. The different case is to allow the motor ‘loose run’ to a stop because the motor is efficaciously disconnected from the circuit.

Building your own H-Bridge Inverter circuit diagram is a fun and rewarding DIY project that can help you take control of the power going to motors in all types of applications. This simple homemade circuit diagram allows you to quickly and easily convert direct current (DC) voltage into alternate current (AC) voltage, which is needed to run electric motors.
