That is one big solenoid! As mentioned, it's not trivial to build such a supply. Perhaps look at industrial motor controllers, maybe surplus on eBay. |

If you are looking for a 3.5kW power supply at 15kHz then it will be very hard to find - or make! |

Building a test stand. You can Oham out the coil but I need to test the full opperation of the valve high and low side. The only way to stest the valve is to put the coil on it and operate it as a unit. |
