SO WHAT DOES STACKING MEAN? It means just what it sounds like, you stack In parallel. If you have a hard time in your area finding capacitors or diodes that are rated that high then you can buy cheap ones and stack them, its much easier though if you buy the rating you need, example; stack each diode or capacitor on top of the other and connect them in parallel. Example: If you stack 2 - 35 amp x 150 v diodes in parallel you will get a 70 amp output, the same withcapacitors. you double your amperage and wattage.

We are trying to make this simple sa anyone can build this It it is still to much tor you we are sorry we have done the best we can for now.

THE ON/OFF PULSER SWITCH FOR RELAY

Now it is time to connect the pulser motor switch. This is on / off set up using a small reed switch, ( Door alarm switch ) it will be used to turn power on and off to the relay coil, this will cause the electromagnet to come on and off, this will also cause the contact arm to move up and down. See also page 6 and 7. So when the relay coil is off the capacitors are charging, and when it is on, it moves the contact ami down and disconnects the 24 vdc battery so it will no longer charge.

Now when it is in the down position, it will turn on the power to the 5 small reed relays in Fig #3. Causing all 5 SCR's to

120 VDC OUTPUT at this point,

As the shaft motor rotates counter clock wise, the magnet comes around and turns on the reed switch turning it off and on, you can replace this pulse reed and motor switch with an electronic on / off system. ( a pulser generator) (it is in the electronics beginners book I told you about earlier, by building an electronic on / off pulser to replace the Reed Switch, the unit will be much quieter. Also place manual on / off switches where needed so you can power up your inverter and turn it off. You will actually need 2 reed and motor switches, this one is the first, and the 2nd one is used for alternating the dc to ac using another relay and 200 amp SCR's. it is all really very simple and not that hard or expensive to build.

The following page shows the use of SCR's to connect the charged capacitors in series to step up the incoming 12 vdc or 24 vdc current.

Please notice that you can use 4 PDT relays to do the same thing which we have fully tested and found the relays do great! We have not fully tested the SCR's yet, but we have done some bench test's and the SCR's look like they will work just fine. If they do not you may know of a better way, please let us know because we do not have the time right now to test and develop the use of SCR's, We are working on more important projects.

Thank you David Waggoner

Radio Shack part # 275 - 214 12 VDC plug- in relay, contacts rated at: 5 A at 125 v

CONNECTING CAPS IN SERIES

Now as seen in page 11, When the relay is turned on, the relay arm will move down and out of charging position and will move to #5 and #9 relay position as shown, this will switch on the SCR'S, and will connect each 24 volt charged capacitor in series and give you an output of 144 volts. Again this will charge #3 The Main Capacitor Bank ( as seen on page 13. ) You can replace with 12 vdc 30 amp auto relays, but is not advisable WARNING: never charge and turn on the SCR's at the same time! It will burn up your SCR's. This is why we use a relay switch #1. Even though the relay will be switching very fast, the charging and the SCR's will be on at different times. If you are going to build an inverter that uses much less wattage, Then again all of these parts can be purchased at any Radio Shack store. Note: For those of you who do not know what an SCR is, It is a Silicon-Controlled Rectifier. You can move a large amount of current with just a very small amount of current just in the milliamps, to turn on the switch to allow the very large current to flow. You can buy 6 amp SCR's at Radio Shack, Play with these first, and learn and then buy the expensive SCR's that you will need for 5,000 watts. Buy 275 amp X 600 volt SCR's for a 5,000 watt unit. Look in your yellow page phone book for electronic suppliers. I found 275 amp SCR's as low as $60 ea.

Side View

These capacitors are the same capacitors as seen on page 10, we did not draw in the other charging connections so you would not get confused, It would look like a bunch of spaghetti, of course this circuit and the circuit on page 10 will all be hooked together, It will be the job of the 4PDT relay to keep them separate.

We are trying to make this as simple for everyone as possible This type of step up transformer / inverter works very well, the capacitors and diodes will last a life time!

C = Cathode, A = Anode, G = Gate. See Radio Shacks getting started in electronics book, it will tell you about SCR's

The Capacitor Step up Transformer

DC to AC Alternator Inverter

For low wattage applications try this below.. For High wattage use the oil drum brush and commutator method.

So you have built everything up to this point and you have even lit 100 watt light bulbs with your new 120 VDC STEP UP CAPACITOR TRANSFORMER. Well it's great for lighting bulbs and running electric heaters, but now you want to run much more, such as TV's, VCRs etc... that use AC. ( NOTE: you can take the AC coil transformers out of each appliance and step down the DC voltage to the required voltage and amps and run on 120 VDC. )

So what we must now do is take that 120 VDC and turn it into 120 volts AC. Which is very simple to do. You can do this electronically or you can do it mechanically by using a store bought 2PDT relay or by building your own relay. We suggest you build your own relay, see bottom drawings. NOTE: If you are not getting 120 VAC output but the voltage is much less, then you must increase the 120 VDC output to a higher voltage until your alternator method is outputting 120 VAC.

Notice: This relay and this motor switch system is not the same as the first. so when you buy your parts you are going to need;
