METHOD OF ESTIMATION OF THE ENERGY EFFICIENCY BY USING ACTIVE POWER FILTER

The method of estimation of decline of grid loadings losses of electric power and electric energy using the power active filter is developed. By the use of the offered method the calculations of energy efficiency of power active filter are executed for the thyristor DC electric drives with zero and bridge circuits of the controlled rectifier, and also for asynchronous electric drives with the thyristor voltage transformer and frequency converter.
