OPTIMIZATION OF ELECTRICAL PARAMETERS OF THE AUTONOMOUS SOURCE OF ELECTRIC POWER SUPPLY OF INTERNAL FIRE-FIGHTING WATER SUPPLY WITH ACCUMULATED BATTERIES

Abstract

The article deals with the problem of providing the internal fire water supply with electrical power and ways to solve it. The existing schemes of voltage conversion using frequency converters and cascaded voltage inverters are analyzed. The parameters of the output voltages of various voltage conversion circuits, their advantages and disadvantages are considered. An active redundant power supply scheme for internal fire-fighting water supply using battery cells and cascade voltage inverters is proposed that ensures the formation of the curve of the output voltage of the AIN and reduces the content of higher harmonics in the voltage at the IF output.
