Description

voltage, comparator 3, first 4 and second 5 key elements, differentiating element b, terminal 7 connecting the first signal source factor, terminal 8 connecting the second signal source factor C, terminal 2 connecting the signal source separator, device output 10, zero potential bus eleven.

The device works as follows.

In the initial state, the first key element 4 is disconnected and the voltage at the output of the generator 2 linearly increasing voltage begins to increase at a speed proportional to the voltage at terminal 9 for connecting the signal source divider.

The inputs of the comparator 3 receive voltages from the output of the generator 2 Line-ramp voltage and from terminal 7 for connecting the first source of the signal factor. At the moment of equality of these voltages, a signal is generated at the output of the paraparameter 3, which locks (opens) the second key element 5, as a result of which the voltage from the B terminal connecting the second signal source factor does not arrive at the output 10 of the device.

The next signal from the clock generator 1 is fed to the differentiating element b, which generates a pulse of a minimum duration. This pulse closes the first key element 4, as a result of which the voltage at the output of the ramp-up generator 2 is reduced to zero and the device returns to its original state. At the end of the pulse at the output of the differentiating element b, the first element 4 is opened and the cycle repeats.

Thus, at the output of the device 10, periodic rectangular pulses are formed, the amplitude of which is determined by the magnitude of the voltage on terminal 8, and the duration is directly proportional to the voltage on terminal 7 and inversely proportional to the voltage on clSF e 9 for any voltage values terminals 7 and 9, including those near and equal to zero.

The period of the pulses at the output 10 of the device is determined by the period of the signals of the clock generator 1, and the duration of these pulses is limited by the time interval in which the first key element 4 is open. The time of the closed state of the first key element 4 is determined by the pulse duration from the output of differentiating element 6, which can be chosen sufficiently short.

The ratio of the pulse duration at the output 10 of the device to their period determines the efficiency of the device.

This ratio may be close to unity, provided that a sufficiently sweet pulse duration from the output of the differentiating element is sufficient. B. Thus, the efficiency of the device can be high.
