AC power supply with tunable induction filter and active parallel compensation function

This work proposes a method of active parallel compensation, which can be implemented using a DC power supply. The second novel aspect of this work is the use of a tunable inductive filter, which is included at the input of the controlled current source. The use of a tunable inductive filter increases the bandwidth of the current source, while at the same time, in the quasi -steady state of the power supply operation, the carrier component (PWM) of the output current of current source remains at a minimum assumed level. The work discusses the design of the electrical system with the proposed power supply and the operating principles of this system and presents the results of simulation and laboratory model tests.
