Hpsp - change the {0," 1) voltage of the heater 15 of the conversion impulses VIHM At the frequency of the transducer at the output of the terminal 16, there is an "O", by which the controlled voltage converter 11 is turned off, while no current is consumed from the source 10 of the backup power supply. At the input terminal 9 of the emergency signal of the power supply network of the EZU 5, the signal "1" is present, permitting the operation of the EZS in normal mode (access, write, read, etc.). This is a normal initial state of the system in which the EZU can operate for a long time.

When the voltage U drops or decreases below the permissible and set by the voltage meter 22 (Fig. 2), the network at the output of the comparator b sets the level L KMVII "1" which, through the input and the second output of the node 7, provides the formation (without delay) at the expense of diode 25) using a pulse front generator (Schmitt trigger) of the emergency power supply network of the ESD 5 "O level with a steep front necessary to transmit it along the communication line from the electrical ignition system to the ESD itself and for the normal (fast) completion of the necessary operations in schemes The control (4) of the EZU 5 for interrupting the operating mode and transferring to the information storage mode. Hold the voltage of the power supply circuit by the first time from its first output to the time (units, milliseconds). of the capacitor 17. At the moment of appearance at the output of the comparator "1, the logical:) element 2 and 16 is transferred to a state at which the output voltage IJiHn of the generator 15 appears at its output including controlled transform 11 Spruce voltage. At the same time, a voltage supply voltage equal to the output voltage of the network rectifier 1 in the presence of a normal network voltage L and sufficient for the operation of the voltage regulator U to operate is started at the output of the reserve rectifier (i.e., on the filter capacitor 17). : .. and providing information storage mode in the circuit (14) of the EZU 5. Moreover, from the time of the accident of the main supply network until the appearance of the output voltage of the backup rectifier 12, the filter capacitor 17 maintains almost the same UFK voltage and is disconnected With a delay corresponding to the first constant time of locking the controlled stabilizer 3, a powerful non-redundant load 4 does not discharge the capacitor 17, and the redundant load 14 uninterruptedly switches to power from the source K) backup power through the voltage converter 1 1.

When restoring the voltage LI, the main supply network, the level of the voltage and the voltage at the inverting input of the comparator 6 exceeds the response threshold U lri and the output of the comparator appears UKIIMII

RC circuits 23 and 24 (Fig. 2) begin to discharge, thereby providing the corresponding delay times. The delay time provided by the first RC circuit 23 is smaller than the delay time provided

Q is the second RC circuit 24, i.e. the activation of the control of its stabilizer 3 is delayed for a shorter time than the formation of a steep front "1 power supply alarm signal disrupting the normal operation mode of the EZU 5. This is necessary in order to

3 and the functional transition of the ESD 5 from the storage mode to the circulation mode. The replenishment of the energy of the filtering capacitor 17 by the delay time provided by the first RC circuit 23 is provided by the network rectifier 1. At the moment when the output of the comparator 6 is level, the O logic 2 and 16 are not restored to the state when "O by which the controlled voltage converter 11 is turned off, but since the non-redundant power is powerful

4 is not included yet, the output voltage of the redundant computer 12 is not, and therefore the voltage of the UFK on the filter capacitor and the FC does not decrease significantly. Thus, the transition of the system from the backup storage mode to the normal operating mode of the power supply from the main AC supply network also occurs smoothly.
