New sight at an old problem of quality of electric energy, of power converters

The problem of interaction of electronics power converters with load and power supplies continues to remain actual because of extending application of power converters and for the lack of its general comprehensible analytical decisions. Here it is possible to allocate three basic aspects of this problem. First, influence of no sinusoidal output voltage of the converter on load. Second, return influence of a no sinusoidal input current single power converter on the power supply. Thirdly, interaction in an obvious kind by means of return influence of no sinusoidal input currents several power converters on a power line in a point of common connection (PCC). The spectral approach actively is developed and is widely used today for the decision of these problems. We develop the uniform integrated approach to all specified problems on the basis of author´s direct methods of calculation (not demanding decisions of the differential equations) of known and new parameters of electromagnetic compatibility of power converters. It is offered to enter into standards on quality of electric energy family of integrated and differential factors of harmonics of a voltage and a current.
