What is H-bridge circuit in a pure sine wave inverter?
In a pure sine wave inverter, the H-bridge circuit acts as the main core. It enables a voltage to be applied across a load in either direction and is used to amplify the input square wave coming from the micro-controller.
How does a pure sine wave inverter work?
A pure sine wave inverter works by using a microcontroller unit to generate a switching signal of 15 KHz. This signal is then converted into AC by an H-bridge circuit. A low pass LC filter circuit is used to block high frequency components, and finally, a transformer unit steps up the voltages.
What is the H bridge used for in this inverter setup?
This simple yet effective setup is very useful in inverter applications where we need to convert high voltage DC to 50 or 60 Hertz AC signal that can be used to drive out AC loads. Such H bridge is quite common in relatively cheap modified square wave inverters though this can also be used in pure sine wave inverters with appropriate modifications.
What can I do to convert this into a full bridge sine wave inverter?
Alternatively, you can also convert this into a full bridge or an H-bridge sine wave inverter by upgrading the mosfets and the trafo rating accordingly. The proposed Arduino inverter circuit could be upgraded to any preferred higher wattage level, simply by upgrading the mosfets and the trafo rating accordingly.
What is an H bridge in a square wave inverter?
In square wave inverters, an H bridge is used to convert high voltage DC to 50 or 60 Hertz AC signal. This simple yet effective setup is very useful in inverter applications where we need to drive AC loads. Such H bridges are quite common in relatively cheap modified square wave inverters.
How Arduino H bridge topology is used in single phase pure sine wave inverter?
H bridge topology is used to convert dc voltage into ac voltage. Step up transformer is used to step up output of H bridge to 220V AC. After step up transformer, a LC filter is used to get pure sine wave from pulsating output wave. Followings are the main components used in single phase pure sine wave inverter using arduino.
