Popis: | Analysis were carried out of power rectifiers’ commutation in balancing transformers at lead control angles, positive effect of shielding angle against surge voltage on the equipment main performance indicators was established, equations and experimental characteristics of this component operation were provided. As a result of theoretical and experimental investigations of the surge protection device operation, a significant positive effect on the quality of switching power rectifiers in the balancing transformer in case of lead control angles was detected. The relationship between the degree of reduction of overvoltage in the input phase voltage of the converter and the capacitance values of the capacitor, the angle of the first switching stage and the lead control angle of the converter were determined. A further study of the unit operation is to establish practically applicable quantitative relations between the specified values. |
