PV Inverter: The H Bridge

A simple animation showing the basic concepts used in changing DC to AC.

Thankyou this helped me clear a Brain fart. Keep them coming😁✌️❤️🤘

Nice animation, generally people fall in problem with the changing direction in source but the actual occurs referring to load.

Thank for this, it real helped to enhance my understanding .

Another cool video thanks for sharing god bless💓

Maybe the high side won't work on h-bridge, because the voltage goes high on the emitter and the base current would turn off?

Hello, Great vid! Thanks for sharing! I have a question regarding common ground. I'm rectifying 110VAC and then inverting it using 4 IGBT and 2 IR2101 MOSFET Drivers. I'm also using an Arduino Micro to control the frequency. Should I connect the ground of the rectified 110V to the ground of the Arduino and Drivers power source?

Why is the sampled AC current from the resistor in the H bridge not rough (sharp spikes and drops) like the clock? How does the AC current at that point have smooth transitions from the peak of the AC waveform to the trough of the AC waveform?

[rafcatthoor]

Dear Jason, the current direction is wrong in both cases! The current shoudld come from the positive electrode of the PV panel, and flow through the transistors in the sense of the transistor arrow. Can you adapt this?

[Gytax]

Wait, but if the Freq Divider provides a square wave to the H bridge, and there's a square wave flowing through the resistor, then what's the point of the H bridge? Using a square wave to generate a square wave? I am not getting something here..

[Eshta]

which simulation program is that ? thank you very much, great video .

[josepeixoto]

I use Mosfets instead, a lot simpler;
IGBTs are a pain to drive, i can't do it reliably, and they are expensive.

[RNAROGER]

Does this produce a usable ac wave form just like inverts with a transformer.

[bayviewboom]

We start with an AC square wave. Then we alternate it through transistor pairs. The PV array sees DC.
So isn't this AC to DC?

i have project in matlab about cascade h bridge inverter
can u help me please ?

[mustaphakamelderkaoui]

hello ;thank you for your effort but your bridge would never work because you need a driver to command the igbt situated at the high side
