Suppression of Ripples of Controllable Rectifiers for Power Supply of Magnetic Systems

A number of requirements are imposed on installations associated with regulated DC sources, including low voltage and current ripple in the load, as well a wide range output variation. Such traditionally made controlled rectifiers or pulse-width converters which ripples always present. The paper considers method for reducing powerful powering magnetic systems based insertion compensating equal magnitude opposite phase to into load circuit. possibility using compensators connected parallel series methods obtaining is shown. Methods given. In order exclude magnetization compensator transformer, it proposed use several versions transformer inclusion compensators. Practical schemes passive (with demagnetizing circuit bifilar winding) analyzed. problem developing multiphase rectifiers, ways solve it, considered. recommendations choosing core material calculating On basis presented theoretical practical considerations design compensators, simulation models have been developed Simulink pack-age MATLAB program. technique studying symmetrical 12-pulse rectifier that has presented. results performed two versions, showed their effectiveness, while scheme was relatively simple economic costs were low. Also, time setting set system presence increases by no more than 3 %, accuracy stability operation do not change.
