DC To AC Power Inverter Design for United Homes
Currently DC to AC inverters are extremely expensive. There are good brands like Schneider, but you have to pay.
Right now there is a need for Alternate power. Solar is proposed. Hurricanes can strike small islands like Jamaica and leave us without main power for weeks. We need back ups.
For a solar set up you need:
- Solar panels
- Batteries
- Charge Controllers (To charge batteries)
- Inverters (To get AC power for batteries)
Regarding DC to AC inverters, there are a few technology out there on wiki. (Later I will comment on them)
I am working on a method myself. I do not know if it will work but I will try to improve and correct.
It is best to have a DC to AC converter that outputs a pure sine wave. Not all inverters are pure, and I think that description is misleading, eg it can by 99.99% pure or 95% pure or 100% pure. I think a percentage would be a more accurate description. Example 99% +- 0.2% pure sine wave.
My design (have not seen any like it so far) but anyways, I want to design one so as to reduce the arm and leg cost that poor people have to pay
The discrete DC to AC (Tesla ) Transformer has these components:
The special transformer
- A Clock Generator (50 Hz x 32)
- A transistor and IC switching system
- (An output clock signal that can be used to synchronize up to 6 devices)
The design concept
The transformer secondary coil is fixed, and it is driven by changing magnetic flux. Mag flux is concentrated by a composite material. (Consider very fine rounded iron filings mixed with a claylike ceramic, just enough to easily transfer a electric or magnetic field without much eddy currents of conduction. i.e. a positive charge placed on one end would be felt at the other end with no electron actually moving from one iron filing to the next. The same if the north pole of a magnet is placed on the composite, the effect is felt on the other end. The composite would be a 3d representation of the magnetic field on a bar magnet. It would be cut in half along the equator so that the coils (eg 2ndary coil) could be placed on the central core. For the first version, the composite material would not be used, just a simple laminated iron core) So the secondary coil is fixed. The primary coil is many discrete coils. Say 16 coils. I have not work out the number of turns each as yet. (I plan to simulate it on a computer program to find the best numbers that give the smoothest sine wave.) The combine total number of turns in all the primary coils would be related to the secondary coil in that 24V on total in outputs 110V. The rate of creation and changing of the driving magnetic field would be generated by how many primary coils are activated. i.e an increase of n turns would cause a certain rate of change of flux, and taking into account the induction of the coils added or removed. The transformer primary coil is separated into 16 non uniform sub coils. A transistor and ic system turn on and off the coils. IC should be a pop out ic to reduce repair cost. That on off system would be drive by a clock source. (The clock signal could be sent eg 1,2,3 + 17,18 beats to another dc to ac converter device where its clock synchronizes its 1,2,3 + 17,18 beats to it. All 32 beats are produced by each clock, only specific beats are communicated. These 32 sub beats occur on each sine wave beat. 16 for the positive and 16 for the negative part of the wave. Each sine wave is produced at 50 Hz. Hopefully the most expensive part is the (Tesla) Transformer.)
I hope this design is simple enough for everyone to understand.
I will try and build it and let you know how it goes.
Let's act on what we agree on now, and argue later on what we don't.
