Description

pa 8 и блока 9 выделени разностной частоты . Импульсы разностной частоты, соответствующие моментам противофазного состо ни выходных напр жений обоих инверторов и соответственно нулевым значени м выходного напр жени преобразовател , запускают блок 10 задержки, а также при помощи формировател импульсов 12 управл ют тиристорами выходного реверсивного выпр мител .pa 8 and difference frequency allocator 9. Differential frequency pulses corresponding to the opposite phase moments of the output voltages of both inverters and, accordingly, zero values of the output voltage of the converter, trigger the delay unit 10, and also control the thyristors of the output reversing rectifier using pulse generator 12.

Амплитуда выходного напр жени определ етс углом сдвига фаз между импульсами на выходе делителей частоты 6 и 7. При этом в зависимости от разности частот следовани указанных импульсов мен етс скорость изменени интервала времени импульсами и соответственно измен етс уровень выходного напр жени , который достигаетс к заданному моменту времени, определ емому блоком 10 задержки.The amplitude of the output voltage is determined by the phase angle between the pulses at the output of frequency dividers 6 and 7. At the same time, depending on the difference in the frequency of the following pulses, the rate of change of the time interval of the pulses changes and the output voltage level changes accordingly. time determined by the block 10 delay.

Таким образом, регулирование амплитуды осуществл етс за счет изменени частоты регулируемого генератора, а регулирование частоты - за счет величины задержки, задаваемой блоком задержки.Thus, the amplitude is controlled by varying the frequency of the adjustable oscillator, and the frequency is controlled by the amount of delay set by the delay unit.
