WebThe power supplies for the ESP convert the industrial ac voltage (220 to 480 V) to pulsating dc voltage in the range of 20,000 to 100,000 V as needed. The supply consists of a step-up transformer, high-voltage rectifiers, and sometimes filter capacitors. The unit may supply either half-wave or full-wave rectified dc voltage. WebSorted by: 1. You're correct that it's not the high voltage itself which ionizes the atoms, but rather the free electrons accelerated by this electric field. In any system at finite temperature, there is a non-zero probability for some atoms to be ionized at any given time. bioelectricity therapy stl
