Как видно из выражений (1) и (2) оптимальный режим детектировани осу- ществл тс лри величине- VQ- О или ТС ,As can be seen from expressions (1) and (2), the optimal mode of detection is carried out with a value of VQ-O or TC,
Недостатком Iоднополупериодных схем преобразовани и детектировани вл врс относительно низкиЖ коэффициент передачи , который устран етс применением двух полупериодных схем.The disadvantage of the full-wave conversion and detection schemes is the relatively low-LJ transmission coefficient, which is eliminated by the use of two half-period circuits.
Наиболее близким ,« изобретению в10 л етс преобразователь переменного напр жени в посто нное, содержащий тран«. сформатор, в котором вторична обмотка имеет среднюю точку, два ключа, подключенные к крайним выводам вторичной The closest to the invention is the 10 V DC / DC converter containing the trans ". a format where the secondary winding has a midpoint, two keys connected to the extreme ends of the secondary
