In addition, a filter compensating device is provided with a control loop for regulating level of supply mains high harmonics, first output of which is connected to first input of a two-bridge rectifier, second output is connected to an amplitude measuring unit, a first comparison unit, first input of which is connected to output of the amplitude measuring unit, to its second input a set unit for available harmonic level is connected. Output of the first comparison unit through an amplitude regulating unit for chosen harmonic is connected to first input of a second comparison unit, to second input of which voltage sensor output is connected, output of the second comparison unit through the voltage regulator of chosen harmonic is connected to input of a system for processing and shaping signals. |
