Description
При изменении крутизны нарастани пилообразного тока генератора 2 пилообразного тока пропорционально мен етс уровень сигнала на выходе трансформатора 5, за счет чего достигаетс стабилизаци положени момента сравнени пилообразного сигнала, снимаемого с выхода вторичной обмотки 7 регулируемого трансформатора 5.When the rise slope of the sawtooth current of the sawtooth generator 2 changes, the signal level at the output of the transformer 5 changes proportionally, thereby stabilizing the position of the moment of comparison of the sawtooth signal removed from the output of the secondary winding 7 of the adjustable transformer 5.
Величина интервала времени, в течение которого триггер 3 находитс в единичном состо нии , определ етс моментом сравнени сигналов на входах устройства сравнени 8 и пропорциональна величине перемещени конденсатора 6.The length of the time interval during which the trigger 3 is in the unit state is determined by the moment of comparison of the signals at the inputs of the comparison device 8 and is proportional to the magnitude of the movement of the capacitor 6.
Предмет изобретени Subject invention
Широтно-импульсный преобразователь, содержащий генератор синхронизирующих импульсов , выход которого подключен к единичному входу триггера и входу генератора пилообразного тока, выход которого соединен с одним из входов устройства сравнени , подключенного выходом к нулевому входу триггера, отличающийс тем, что, с целью повышени точности преобразовани , выход генератора пилообразного тока подключен к второму входу устройства сравнени через регулируемый трансформатор.A pulse width converter that contains a clock pulse generator, the output of which is connected to a single trigger input and a sawtooth current generator, the output of which is connected to one of the inputs of the comparator connected to the zero input of a trigger, characterized in that, to improve the accuracy of the conversion The output of the sawtooth generator is connected to the second input of the comparator via an adjustable transformer.
