METHOD FOR GROUP CONTROL OF SWITCH VOLTAGE ADJUSTERS (VERSIONS)

摘要

FIELD: electricity. ^ SUBSTANCE: in a method for group control of individually loaded switch voltage adjusters connected to a single power supply, a common period of pulse-length modulation, independent variation of pulse duration during which the adjuster activates the load to power supply; in each modulation period, the adjusters are divided on two groups equal for total pulse durations or total products of load current and pulse duration of the adjuster, and the first group loads in the ascending order of input currents and then the second group loads in the decreasing order of currents are connected to the power so that to combine a pulse start of every adjuster with pulse termination of the previous adjuster. ^ EFFECT: higher power factor of switch voltage adjusters. ^ 2 cl, 3 dwg, 2 tbl
