Abstract
A high voltage amplifier and a method of assembling and of operating a high voltage amplifier are described. The device includes a first metal-oxide-semiconductor field-effect transistor (MOSFET) driven by a first gate drive circuit. The device also includes a second MOSFET driven by a second gate drive circuit and a first optocoupler coupled to the second gate drive circuit. The first MOSFET and the second MOSFET of the high voltage amplifier drive a first output voltage.
