I have taken a 6 inch plasma ball and extracted 150 DC volts off of its surface. Its to long as to go into details. I need a circuit that will allow me to step down this voltage and regulate it so its output is 12 volts DC. I don't wish to use a lot of power robbing resistors. I see a lot of buck step down converters on the market but not one that will take 150 DC volts down to 12 DC volts.
All help appreciated.
