The work is devoted to the development of a circuit model of AC voltage regulator with the time of autonomous operation of up to several tens of seconds. The essence of the proposed the proposed circuit modification of the device is to replace the batteries that supply the stabilizer, with an ionistor module. The main advantages of ionistors are the ability to discharge to zero, charge and discharge by large currents, a simple charge system similar to the charge of a capacitor, high power density, and a large number of charge-discharge cycles, close to one million. In order to achieve maximum time of autonomous operation of AC voltage regulator, parallel-connected DC−DC boost converter on the pulse-duration modulation controllers LT1243 were added to the device circuit. Verification of the effectiveness of the proposed solution was carried out using circuit simulation and full-scale tests. The LTspice software package was used to simulate the discharge of the ionistor module. To carry out full-scale experiments, we used AC voltage regulator based on an uninterruptible power supply from Ippon Black Office 600 with a power of 300 W using an 83 F ionistor module with the maximum possible voltage of 16.2 V. According to the results of full-scale experiments, it was found that the time of autonomous operation of AC voltage regulator containing new circuit solutions was 86 s in the case of an active load of 100 W and 29 s in the case of an active load of 300 W.
