Ways, which reduce modulating (multiplicative) interferences, arising in ship networks of a secondary electric power supply and having a negative influence on the transmitting-receiving equipment are considered in the paper. There is an undesirable modulation of radio signals by frequencies of harmonics of a power line while currents of high frequency are passing through diodes of rectifiers. An optimum combination of parameters of filtering elements has been found on the example of the scheme of modelling to neutralize interferences of a similar kind in low-power transmitting-receiving devices.
Рассматриваются способы уменьшения модулирующих (мультипликативных) помех, возникающих в судовых сетях вторичного питания и оказывающих негативное влияние на приемопередающее оборудование: при прохождении токов высокой частоты через диоды выпрямителей возникает нежелательная модуляция радиосигналов частотами гармоник питающей сети. На примере схемы моделирования найдено оптимальное сочетание параметров фильтрующих элементов для компенсации помех подобного вида в маломощных приемопередающих устройствах. Библиогр. 4. Ил. 4.
