VOLTAGE CONVERTER Russian patent published in 1994 - IPC

FIELD: automatic equipment. SUBSTANCE: voltage converter has a power amplifier, control unit, frequency divider in the form of a block of binary counters connected to rectifiers with filters to produce the level of voltage of each frequency. All coincidence circuits, except for the first one, are NAND circuits, connected to which are the inverter outputs of each subsequent frequency and the voltage level of the preceding frequency applied to the OR circuit. Depending on the nature of variation of the operating and load conditions, one of the frequencies is applied to the control block from the frequency divider via the analysis block. EFFECT: expanded functional abilities and enhanced reliability indices due to operation not at a fixed frequency, but at a variable one, depending on the load conditions and operating conditions. 2 dwg
