Abstract
The paper deals with the approach to application of inverter-type converters for powering the cathode and forming the control voltage of electron beam guns to reduce the overall dimensions of the block of bias and power of the cathode. This enables neutralizing the negative impact of leakage inductance of high-potential transformer, which increases with introduction of insulation between the windings to ensure the potential decoupling. Keywords: electron beam welding, electron beam gun, cathode power, bias voltage, inverter, potential decoupling
