By M.M. Dudkin, L.I. Tsytovich and A.S. Nesterov


AbstractOne of the possible solutions leading to higher interference immunity and electromagnetic compatibility of control systems of power semiconductor converters (SC) due to the usage of integrating scanning conversion is given. Integrating adaptive synchronizing units, phase shifting adevices and analog-digital converters, which are distinguished by a high interference immunity to the external interference signals, accuracy and ability to adapt to the changing parameters of mains voltage are considered. It has been shown that integrating scanning conversion in the base of construction of control systems of power semiconductor converters contributes to a high level of interference immunity and adaptation of SC to the inconsistent parameters of mains voltage in the stationary and autonomic-based power-supply systems, outgoing with this considerably the analogous indicators of the commercial power converters of home-made and imported production with the control systems constructed on the principle of momentary values sampling of information coordinate
