Cool video. Question - the fact that in the last animation arrows grow bigger/smaller bit by bit, not just waiting for the full cycle (like in the first animation that showed it working with switching only when the arrow had maximum length), is by design and it shows the green voltage graph that is "closer to sinusoid"? I just want to make sure I understood it properly.

Yes, this is to make it look more like a sine wave. To make it look even more like a sine wave, the switching frequency would be much faster.

@@EugeneKhutoryansky Yes - but higher frequency has it's drawbacks as well. Hence why standard AC current is delivered in 50 or 60 Hz throughout the world. Some ships (Soviet Submarines for example) used 300 or 400 Hz. I do not remember all the pros and cons of high frequency, but there was a good video about it on RSD Academy. And making (especially in old times) elements that would switch very very fast would reduce their lifespans. One of the first grids was 133 Hz from memory.

@EugeneKhutoryansky

Жыл бұрын

The AC output would still be 60 Hz or 50 Hz. I was referring to the switching frequency. You can have a switching frequency in the kHz range, and still produce and output of 60 Hz or 50 Hz.

@atzuras

Жыл бұрын

Switches do have heating and power loss when switching.. Because they are Power MOS or Solid State Relays so frequency does have some limitation on the efficiency, size or power. Plus some snubber circuits to protect the switches themselves. Not cheap. But many times you do not need a perfect sinusoidal wave, just a stable frequency It is not the same to run water pumps from a battery that an electric car. And for the russian submarines, I guess a 400Hz switching frequency noise may be easy to track if you know what you are looking for. EM noise is much worse at higher frequency.

Beautiful animation video my mentor ! This was an example of brilliant circuit design and demonstration... Will you please make a video on tidal locking, tidal tearing up of a moon and tidal hill sphere... I still can't understand why the moons goes aways from us 4cm each day.... This is only possible if the moon's orbital velocity around the Earth keeps on increasing. But how the tidal forces from the earth are accelerating moon's orbital velocity? How the tidal forces can rip apart the moon if it tends to fall on earth? Are tidal forces same as gravitational force or it is something different? Is tidal force the reason of why galaxies are moving away from one another rather than dark energy?

@EugeneKhutoryansky

Жыл бұрын

Thanks for the compliment. If you want to use solar panels to generate power for an electric utility grid, then you need a 3 phase version of this circuit. Also, the inductor for each phase may be replaced with the primary coil of a transformer, with the load being on the secondary side of this 3 phase transformer. The transformer is needed to change the voltage, so that it matches the voltage of electric utility grid.

@@EugeneKhutoryansky Thanks for replying. After thinking about the video I now understand how an inverter can be bidirectional (to charge batteries from grid). Because there is nothing in the circuit that makes it one directional. Correct me if I am wrong. Btw, do all the PV inverters have transformers? I’ve heard there are inverters that are transformer-less. Probably to use less materials.

I was going to Tosche Station to pick up some power inverters

OK I'll be that guy. What is the purpose of the tree log in the inductor? Is the from an Iron Oak?

You are showing current flowing two directions through the battery. Shouldn't it be only one way and the switching of mosfet pairs give the two different circuits / directions independent of the battery?

@EugeneKhutoryansky

The video shows it correctly. The inductor forces the current to momentarily charge the battery. Otherwise, either the current through the inductor would change instantaneously, or the current would flow through a mosfet when it is blocking.

The animation is correct, and this is why no one else complained about it. The current in an inductor can't change instantaneously. Therefore, when the transistors change their on / off status, the current must initially flow backwards into the DC source.
