New family of AC regulators with the switched quasi-impedance of power supply or load

The new family of AC voltage regulators based on the switching quasi-impedance of power supply or load is offered. Such AC-AC converters are intended for construction of conditioners of voltage quality, regulators of a soft start of induction motors, compensators of a reactive power, active filters of harmonics, devices of balancing of three-phase circuits, compensators of voltage sags in electric power distribution systems. Results of mathematical modeling and analytical calculation of RMS values by fundamentals of the currents and voltage are given.
