Description
(54) СГЛАЖИВАЮЩИЙ ФИЛЬТР(54) SMOOTH FILTER
pa, a дроссель с обмотками 4 и 5 и конденсатор 6 - второе звено фильтра.pa, a choke with windings 4 and 5 and a capacitor 6 - the second link of the filter.
Фильтр работает следующим образом.The filter works as follows.
Выпр мленный ток содержит посто нную и переменные составл ющие (гармоники) различных частот. Переменные составл ющие выпр мленного тока, протека через обмотки 1 и 5, конденсатор 3 и обмотки 2 и 4, конденсатор 6, образуют потоки самоиндукции и взаимоиндукции. Так как обмотки 1 и 2 (4 и 5) расположены в одном сердечнике, то поток взаимоиндукции обмотки 1 (5), пересека обмотку 2 (4), индуцирует в ней дополнительное переменное напр жение. Это эквивалентно введению в цепь нагрузки компенсирующего переменного напр жени , основна гармоника которого противоположна по фазе переменной составл ющей выпр мленного тока на нагрузке . Противоположность фаз обеспечиваетс встречным включением обмоток дросселей , т. е. выводы основной и дополнительной обмоток каждого дроссел соедин ютс таким образом, чтобы магнитные потоки самоиндукции и взаимоиндукции были направлены в противоположные стороны. Благодар этому кбэффициент сглаживани предлагаемого фильтра увеличиваетс в 2 - 2,5 раза.The rectified current contains a constant and variable components (harmonics) of different frequencies. The variable components of the rectified current, flowed through the windings 1 and 5, the capacitor 3 and the windings 2 and 4, the capacitor 6, form self-induction and mutual induction currents. Since windings 1 and 2 (4 and 5) are located in the same core, the mutual induction flow of winding 1 (5), crossing winding 2 (4), induces additional alternating voltage in it. This is equivalent to introducing into the load circuit a compensating alternating voltage, the main harmonic of which is opposite in phase to the variable component of the rectified current on the load. The opposite of the phases is provided by counter-switching of the windings of the chokes, i.e. the conclusions of the main and additional windings of each throttle are connected so that the magnetic flux of self-induction and mutual induction are directed in opposite directions. Due to this, the smoothing factor of the proposed filter is increased by 2-2.5 times.
