6 voltages, resistors 7, charge voltage, pulse-pulse modules 8, inverters 9, control voltage block 10,

The pulse-width modulus of the mountains 8, to the inputs of which the voltage of the nodal shank and the periodic voltage from the control voltage 1O, produces pulses whose duration T is a given function of the voltage of the nodal point. The type of functional relationship (s) is given by the form of the periodic stress. These pulses are applied to the control inputs of the switching keys 4, which, in the presence of pulses, are in the closed state, and in the absence of them in the open state. Switching keys 4 and 5 switching keys with the help of inverter 9 are controlled in antiphase, t, e when switching keys 4 are closed, B keys are charged and closed, and vice versa, In the key closed time interval

4 switching commutator 3 is connected to the nodal point and the value of the capacitance at the nodal point is equal to the sum capacitive, tey of the switched capacitor 3 and the capacitor 2 KS-; At the time of unlocking the key 4 switching closes

5, yes, and switched capacitor 3 is connected to the charging resistors, yes. In the time interval of the closed state of the key 5, the charging and switching capacitor 3 is charged from the repeaters 6 of the voltage of the adjacent node points through the switching power 7 that is charged, such that the voltage on the non-switched 2 and switching capacitors are equal at each time instant. In this time interval, the capacitance value at the nodal point is equal to the capacitance of a certain mutated Capacitor 2. In the circuit of the switch 4, the voltage jumps at the nodal point are not aerated because the voltage on the conduit; To ensure equal voltage across each MOMeiiT of time, the resistance of resistors 7 on the charge should be calculated using the formula

The proposed device automatically eliminates the recharging of 1 C-grid capacitors, which occurs during periodic switching of these capacitors and is the cause of voltage surges at the nodal points of the RC grid. ki and significantly increases the accuracy of solving nonlinear problems of gender theory. The device effectively solves nonlinear partial differential equations, in which the coefficients are the arbitrarily given function of the desired NepeMetina.
