The shaper works as follows.

When the control signal is applied to the charging control key 2, the key is unlocked and the capacitors 3 and A of the bridge are charged from the constant voltage source 1 through the resistors 5 and 6, and the capacitor 15 of the multiplying unit (UB) is charged through the resistors 11 and 12 . The voltage on the capacitors 3 and 4 is equal to the voltage of the source 1, the key 2 is locked. The formation of the output voltage U., .. o6ecwblX

those. voltage multiplication factor is three. Diode 13 is closed when the key 14 is unlocked, and through the open diodes of the other FMs, a connection is made to the common point of the device. If we now apply a control signal to the bit switch 9, then the output voltage of the driver is connected to the control circuit of the controlled device 8.

Thus, the formation of pulses of arbitrary shape and amplitude is provided (some variants are presented in Fig. 2). The increasing output voltage is generated when the UB keys are unlocked, and the decrease is due to their locking. The determined supply of control signals to the control inputs of the control keys ensures the specified formation of the output signal.
