It is shown that the correct solution of the problem of determining the full power of a multiphase power supply system is accompanied by finding the interrelated values ​​of the minimum possible linear losses and active current. Developed and verified active filtering strategies in the coordinate system of the two wattmeter method that minimize power losses of a three-phase three-wire transmission line with different values ​​of its resistances. A method of determining two components of the integral power of the unbalance by performing real-time algebraic operations on the oscillating components of the instantaneous power and αβ-coordinates of the voltage synchronized with the three-phase network is proposed. New formulas for calculating the four power components of the unbalance of three-phase, four-wire power supply systems based on the measurement of active and reactive powers of individual phases, which can be used to form compensation signals in distributed active filtering with centralized control, are substantiated. A new structural scheme of PAF control with extended functionality and increased speed is proposed. A study of step-up and step-down type pulse regulators operating on a battery showed that with the presence of a battery at the output, pulse voltage regulators will work in the current regulator mode; the nature of the adjustment characteristic and the adjustment range depends on the type of regulator and the value of the voltage on the battery; the maximum power from the source will be selected at a certain value of the duty cycle of the power transistor control pulses, which is determined by the type of regulator and the value of the battery voltage.
