brumi said:Here there is a simple schematics.For high power you must add a power mosfet to the output.Be careful with HHO generator remember to add a flashback protector and flashback valve, it's dangerous work with hidrogen.
brumi said:The 1458 is a general porpouse operational amplifier.
The capacitor "c" and the resistor "r" determine the operating frequency.
The 10k variable resistor adjust simetry, 50% on - 50% off . Or adjust it to your needs.
See the schematics using the mosfet .
Added after 13 minutes:
Sorry , I forget the schematics.
You must use square output.
And +B is the voltage needed for the load.
The mosfet must be for the load and voltage you need.
The HHO cell use low voltage 12/ 20 volts and N ampere
You need a mosfet for 50/60 volts and Nx2 amperes
The IRF520 Mosfet is very old. Whoever still sells it might charge much more than it costs (RadioShack). Much better Mosfets are available and can drive many more Amps.galveston said:i've learned that an IRF540 delivers 10A. Queston: If two of these are hooked in paralell, does that deliver 20A to the load?
