Description

one

The invention relates to a pulse technique.

A linearly varying voltage generator is known, which contains charge, discharge, and current stabilizing transistors, a parallel / C-chain of independent compensation, which forms a capacitor, and turns off a diode. A disadvantage of the known generator is the low utilization rate of the power source.

In the proposed generator, this disadvantage is eliminated due to the fact that the independent compensation circuit is connected between the anode of the disconnecting diode and the base of the current-stabilizing transistor connected through a resistor to the collector of the charging transistor.

ha the drawing shows a diagram of a generator of a linearly varying voltage.

The generator contains charge 1, discharge 2 and current-stabilizing 3 transistors, a parallel / C-chain of capacitor 4 and resistor 5, connected to the base circuit of transistor 3, forming capacitor 6, diode 7, capacitor 8, resistor I connected between the base of transistor 3 and collector transistor 1.

In the initial state, the transistors Y and 2 are open with a negative control pulse, the capacitor 6 is discharged, and the capacitors 4 and 8 are charged. At the end of the control pulse, the transistors 1 and 2 close, the capacitor 6 starts to charge. The voltage at the anode of diode 7 becomes smaller than at the cathode, diode 7 is closed, and the base current of transistor 3 is closed to capacitor 8. The discharge of capacitor 8 and the charge of capacitor 6 cause the charge current to decrease. The discharge of capacitor 4 on resistor 5 increases the collector current of transistor 1, i.e. the process of charging capacitor 6 is linearized.
